Does PRP Work for Back Pain. Disc, Facet and Sacroiliac Injections, and Why We Mostly Say No
For most back pain, no, and we decline most enquiries about it. The evidence for PRP into a spinal disc is a single double-blind trial of 16 patients that missed its primary endpoint, small series, and a reported disc infection requiring surgery. NICE advises against spinal injections for non-specific low back pain. The treatment for most back pain is movement.
Key points
A 2022 double-blind randomised trial in the Journal of Clinical Medicine gave 16 patients with discogenic low back pain an intradiscal injection of PRP releasate or corticosteroid. The primary outcome, change in pain at 8 weeks, did not differ between groups, with a disability score advantage for PRP at 26 weeks in a secondary analysis.
A 2022 single-arm study of 31 patients given one intradiscal PRP injection reported that 71 percent were classed as successes over 48 weeks and that 1 patient required surgery 2 weeks after injection for intervertebral discitis, an infection of the disc.
A meta-analysis of intradiscal PRP could find only 3 studies to pool, 1 randomised trial and 2 observational studies, and found pain reduced at 2 and 6 months but not at 1 month.
NICE guideline NG59 on low back pain and sciatica advises against spinal injections for non-specific low back pain, recommending exercise, manual therapy within an exercise programme and psychological support instead.

Why back pain is different from a knee or a tendon
PRP has trial evidence in the knee, in several tendons and in the carpal tunnel, and the temptation is to assume that what helps a joint will help a spine. The spine is different in 3 ways that matter. First, most back pain has no single identifiable source. NICE calls it non-specific, meaning it cannot be attributed to a disc, a facet joint or a sacroiliac joint with any confidence, and an injection needs a target. Second, the structures that can be injected sit next to the spinal cord, the nerve roots and the major vessels, so the procedure risk is of a different order from a knee. Third, the disc is avascular, meaning it has almost no blood supply, which makes it slow to heal and dangerously slow to clear an infection introduced by a needle.
The natural history is also different. Most episodes of low back pain settle within 6 to 12 weeks with movement and reassurance, which means any injection given in that window takes credit for a recovery that was coming anyway. That is why NICE guideline NG59 recommends exercise, manual therapy as part of an exercise programme and psychological approaches for persistent pain, and advises against spinal injections for non-specific low back pain. A clinic offering PRP for a bad back is offering a procedure the national guideline says not to do, on evidence the next section sets out. The non-surgical options that do exist are worth knowing before anyone reaches for a needle.
What the disc evidence actually is
The strongest study is the 2022 double-blind randomised trial in the Journal of Clinical Medicine from Mie University in Japan. Sixteen patients with discogenic low back pain, confirmed by imaging and discography, received an intradiscal injection of either PRP releasate or corticosteroid. The primary outcome was change in pain at 8 weeks, and it did not differ between the 2 groups. In secondary analyses the PRP group had a better disability score at 26 weeks and better walking ability at 4 and 8 weeks. Sixteen patients is a pilot, the primary endpoint was missed, and the comparator was steroid rather than saline.
The other studies are smaller or uncontrolled. A 2022 single-arm study of 31 patients given a single intradiscal PRP injection reported that 22, or 71 percent, were classed as successes over 48 weeks, and that 1 patient developed discitis, infection of the disc, requiring surgery 2 weeks after injection. A meta-analysis attempting to pool the evidence found only 3 eligible studies, 1 randomised and 2 observational, and reported pain reduction at 2 and 6 months but not 1 month. A 2016 review in International Orthopaedics called intradiscal PRP safe and possibly effective and asked for the trials that, 10 years later, are still largely missing.

Facet joints, sacroiliac joints and the rest
The facet joints are the small paired joints at the back of each spinal segment, and the sacroiliac joints connect the base of the spine to the pelvis. Both can cause back pain, both are injected with steroid in pain clinics, and both have been injected with PRP in small studies. The literature consists of a small randomised comparison of PRP against steroid in the lumbar facets, a small randomised comparison in the sacroiliac joint, and case series, with follow-up of months and patient numbers in the dozens. None reaches the standard of the knee or carpal tunnel evidence, and none justifies a course sold to a patient whose pain source has not been confirmed by a diagnostic block.
The honest position is that facet and sacroiliac PRP are experimental treatments that a pain specialist might reasonably discuss with a patient who has a confirmed pain source, has exhausted the exercise-based treatment NICE recommends, has had steroid that faded, and understands the evidence is thin. That patient exists. He or she is not the person answering an advertisement for regenerative back pain treatment, and a clinic that injects a spine without a diagnostic block, imaging guidance and a pain specialist is doing something the evidence does not support in a place where the risks are real.
What actually treats back pain
NICE guideline NG59 is clear and it is not what most people want to hear. For non-specific low back pain with or without sciatica the recommendations are to stay active, to use a structured exercise programme tailored to the individual, to consider manual therapy only as part of that programme, and to add a psychological approach for persistent pain that is limiting life. It advises against belts, traction, acupuncture, ultrasound and, for non-specific pain, spinal injections. Paracetamol alone is not recommended, and opioids are to be avoided for chronic pain. Radiofrequency denervation is an option for confirmed facet pain after a positive diagnostic block, and surgery is reserved for specific structural problems with nerve compression.
That guideline exists because the trials of movement-based treatment are large and the trials of injections are small, and because the natural history of back pain is recovery. A patient with persistent back pain who has not yet done a proper exercise-based programme with a physiotherapist has not yet had first-line treatment, and the injection conversation, whatever is in the syringe, comes after that and only for a confirmed source.
A back pain check before any injection
Work through this before booking anything, including here.
Do you have any of the following. Numbness in the saddle area, new difficulty passing urine or controlling the bowels, weakness in both legs, or back pain with fever or unexplained weight loss. Any of these is a same-day A and E visit, not an injection.
Has the pain been there under 12 weeks. Most episodes settle in that time with movement, and no injection improves on that.
Have you done a structured exercise programme with a physiotherapist for at least 3 months. If not, that is first-line treatment and comes before any needle.
Has a specific source been confirmed, by MRI and, for facet or sacroiliac pain, a diagnostic block that relieved the pain. Without that there is no target.
Is a pain specialist or spinal specialist involved, with imaging guidance. If the answer is a regenerative clinic without either, decline.
Our doctors put it this way. The spine is where we say no most often, and we say it before people spend anything. The evidence for PRP in a disc is 16 patients and a missed endpoint, and the risk is an infection in a structure that cannot clear it. Back pain is treated by moving, and we would rather send you to a physiotherapist than into a needle.
Message us on WhatsApp with how long the pain has lasted, what you have tried, and any imaging, and a doctor will give you a straight answer, which for most backs is a referral to physiotherapy or a pain specialist rather than a booking.
What PRP does not do for the back
PRP does not have a randomised trial that met its primary endpoint in the spine, does not have a placebo comparison in the disc, and does not have evidence in the facet or sacroiliac joints beyond small studies. It does not regenerate a degenerate disc in any way shown in patients, and the 1 study that imaged discs found no change in degeneration grade. It carries a documented risk of discitis, an infection in a structure with almost no blood supply, and the procedure sits beside the spinal cord and nerve roots. It does not replace the exercise-based treatment NICE recommends, and it is not commissioned by the NHS for any spinal indication.
What spinal injections cost, and what the wrong one costs
Specialist central London clinics commonly charge from around £780 to £900 or more per image-guided PRP injection including assessment, and spinal procedures through pain clinics carry higher fees for the imaging, the setting and the specialist involved. A course of physiotherapy costs a fraction of a single spinal injection and is the treatment with the evidence.
The reframing is the disc that gets infected. A single intradiscal PRP injection that goes well costs its fee. One that introduces discitis costs weeks in hospital, intravenous antibiotics, possibly surgery, and a disc that is worse than before. The 31-patient series recorded 1 such case. Against that, a physiotherapy programme that NICE recommends costs less, carries no such risk, and is what the guideline says to do first.
Care at The London PRP Clinic by The Wellness is doctor-led and priced below flagship central London rates, but for back pain the likely outcome of the free suitability review is a referral to physiotherapy or a pain specialist, and we would rather say so here than take a fee.
Ask us what would help your back on WhatsApp and we will explain what the review covers.
The free suitability review
Every enquiry here starts with a free, doctor-led suitability review rather than a booking. A GMC-registered doctor takes a history, screens for the red flags that need emergency care, reviews any imaging, and gives one of two answers. Either you are approved for treatment, which for the spine means a confirmed source, exhausted first-line care and a pain specialist involved, with the thin evidence set out plainly, or you are not approved, with an honest explanation of what would serve you better, which for most back pain is a structured exercise programme and, where needed, a pain or spinal specialist.
We decline a meaningful share of the people who enquire. For back pain that share is nearly all of them, and we publish this article so that fewer people pay elsewhere for what the evidence does not support.

Frequently asked questions
Does PRP work for back pain
Not on current evidence. The only double-blind randomised trial of PRP into a disc, 16 patients, missed its primary pain endpoint at 8 weeks. Facet and sacroiliac PRP have small studies only. NICE advises against spinal injections for non-specific low back pain and recommends exercise-based treatment.
Is PRP safe for the spine
Less safe than in a joint. A 31-patient study of intradiscal PRP recorded 1 case of discitis, infection of the disc, requiring surgery 2 weeks after injection. The disc has almost no blood supply to clear infection, and the injection sits beside the spinal cord and nerve roots. Any spinal injection needs imaging guidance and a specialist.
What does NICE recommend for back pain
NICE guideline NG59 recommends staying active, a structured exercise programme, manual therapy only within that programme, and psychological approaches for persistent pain. It advises against spinal injections for non-specific low back pain, against belts, traction and acupuncture, and reserves radiofrequency denervation for confirmed facet pain after a diagnostic block.
Does PRP regenerate a degenerate disc
Not in patients. Laboratory and animal studies show effects on disc cells, but the 1 trial that graded disc degeneration on MRI after PRP found no change between groups. Any clinic claiming disc regeneration should be asked for the imaging.
Can PRP help sciatica
Sciatica is nerve root compression, usually from a disc bulge, and the evidence-based options are exercise, time, an epidural steroid injection for severe cases and surgery for persistent nerve compression. PRP has no trial evidence for sciatica and is not part of the NICE pathway.
When should I go to A and E with back pain
Immediately if there is numbness in the saddle area, new difficulty passing urine or controlling the bowels, weakness in both legs, or back pain with fever, unexplained weight loss or a history of cancer. These can indicate nerve compression or infection and need same-day assessment.
