What medical treatments are there for RSI, carpal tunnel and tendon pain?
Quick answer: Doctors usually start with rest from the aggravating task, activity changes, painkillers and sometimes a splint. If that does not work, a cortisone (corticosteroid) shot can give short-term relief for carpal tunnel syndrome and De Quervain's. Surgery is for cases that keep getting worse or do not respond. For tennis elbow, shots and PRP have weaker evidence. Talk to your doctor before choosing any of these.

"RSI" is not one diagnosis, so the treatment depends on what the problem is. This page covers the main medical options for carpal tunnel syndrome, De Quervain's, trigger finger and tennis elbow, and how well each is supported. It cannot say what is right for you. Your doctor can.
What do doctors usually try first?
For general RSI, the NHS says most people get better without further treatment. It advises staying active, starting with less and building up slowly, and talking to your employer about changing your work. Painkillers come next. If symptoms do not go away, a GP can suggest physiotherapy, occupational therapy or steroid injections. The NHS says surgery is rarely needed and only if RSI is very severe.
For carpal tunnel syndrome, the first steps are a night splint and avoiding activities that hold the wrist bent for long periods (AAOS). See wrist splints for RSI.
Do painkillers and NSAIDs help?
They can ease pain for a while. The NHS lists paracetamol, or anti-inflammatory painkillers such as ibuprofen, as options for RSI. These come as tablets or as gels rubbed on the sore area. A pharmacist can advise. For tennis elbow, the NHS mentions paracetamol and an anti-inflammatory gel, and notes that ibuprofen gel is flammable, so keep it away from smoking and naked flames.
The limit is that pain relief is not a fix. For carpal tunnel, the NHS says there is little evidence that paracetamol or ibuprofen treat the cause. The German health information service IQWiG says studies so far show NSAIDs do not relieve carpal tunnel pain enough. Mixed evidence overall: fine for a flare, weak as a plan. Check with a doctor or pharmacist before you take them regularly.
Do cortisone shots help carpal tunnel and De Quervain's?
A corticosteroid injection reduces swelling around the nerve or tendon. For carpal tunnel, a 2023 Cochrane review of 14 trials with 994 people found that it probably improves symptoms and function for up to three months, with benefit still seen at six months, and probably slightly reduces the need for surgery at one year. Serious side effects were rare. In one included study, 65% of injected people had mild to moderate pain lasting under two weeks, and about 9% had local swelling. That is good evidence for short-term relief in mild to moderate cases. It is not a cure: the NHS says symptoms can return after a few months and another injection may be needed.
"An injection of cortisone, most of us feel, is not going to ever cure carpal tunnel syndrome, but it could last even all the way up to a year of symptom-free, so I use that a lot to get people to where they want to be for their surgery." — Douglas Hutchinson, MD, orthopedic hand specialist, University of Utah Health, Carpal Tunnel Treatment Options, The Scope, University of Utah Health, December 2015 (updated April 2025)
For De Quervain's (pain on the thumb side of the wrist), a systematic review found moderate evidence of short-term benefit from an injection, and adding a thumb splint seems to help. That is some evidence, and the trials were small. Whether to have an injection is a decision for you and your doctor.
When is carpal tunnel surgery considered?
The NHS says surgery is considered if symptoms are getting worse and other treatments have not worked. AAOS adds that it may be recommended if there are significant nerve changes on testing, or in long-standing cases with constant numbness or wasting of the thumb muscle. A 2024 Cochrane review comparing injection with surgery found both groups improved in every study, but the evidence was too uncertain to say which is better. This is a decision to make with a specialist.
A 2025 trial in 31 Dutch hospitals compared surgery first with an injection first, in 934 people with carpal tunnel syndrome. It did not compare surgery with splints or exercises. About 61% of the surgery group and 45% of the injection group had recovered at 18 months on the trial's symptom scale, so many people in both groups had not.
"In patients with carpal tunnel syndrome, initiating treatment with surgery offers a higher chance of recovery after 18 months compared with starting with a corticosteroid injection, even with the possibility of additional interventions." — Palmbergen, Beekman, Verhamme and colleagues, Dutch carpal tunnel study group, Surgery versus corticosteroid injection for carpal tunnel syndrome (DISTRICTS), The Lancet, June 2025
How is carpal tunnel release done, and how long is recovery?
The surgeon cuts the ligament that roofs the carpal tunnel to take pressure off the nerve. In open surgery this is done through a small cut in the palm. In endoscopic surgery it is done through one or two smaller cuts, using a camera. AAOS says the two give similar outcomes, with different benefits and risks. The NHS says the operation takes about 20 minutes under local anaesthetic, with no overnight stay, and that it usually cures carpal tunnel syndrome.
AAOS gives a rough course. Night symptoms often improve in the first week. Palm soreness can last weeks to months. Grip and pinch strength usually return by about 2 to 3 months, longer if the nerve was in poor shape before. In severe cases numbness can take 6 to 12 months to improve, and some people do not recover fully. Full recovery can take up to a year. The NHS says about a month to return to normal activities. Ask your surgeon about driving and work.
What is trigger finger release?
In trigger finger, a finger catches or locks when you bend it. AAOS lists rest from gripping, night splinting, NSAIDs and a steroid injection as first steps. Up to three injections may be given, and they are less likely to work with diabetes, long-standing triggering or trigger thumb. A Cochrane review found steroid plus local anaesthetic beat anaesthetic alone in the short term, but from two small, poor-quality trials. If injections fail, release surgery opens the tight pulley at the base of the finger, usually as an outpatient under local anaesthetic. AAOS says swelling and stiffness can take 4 to 6 months to settle, and full recovery averages about 6 months. AAOS also notes that blood sugar may rise for about 10 to 14 days after an injection in people with diabetes who take insulin, so tell your doctor if that applies to you.
Do injections or PRP help tennis elbow?
The NHS says tennis elbow usually improves with rest, but can last over a year. Evidence for injections is weaker than people expect. In a 2013 JAMA trial of 165 people whose tennis elbow had lasted over six weeks, those given a corticosteroid injection did worse at one year than those given placebo, and the problem came back more often (54% versus 12%). AAOS says steroids should be used very sparingly because they can weaken the tendon attachment over time.
Platelet-rich plasma (PRP) uses your own blood. AAOS calls study results inconclusive but sometimes promising. A 2021 Cochrane review of 32 studies with 2,337 people found no clinically meaningful difference from placebo at three months, and no meaningful benefit at six or twelve months. Its authors said the data do not support PRP or blood injections. The NHS says surgery can be considered after 6 to 12 months. AAOS reports 80 to 90% success but says loss of strength is not uncommon.
How strong is the evidence for each treatment?
This table sums up the sections above. Talk to your doctor about which of these fits your diagnosis.
| Treatment | Used for | Evidence | Main limit |
|---|---|---|---|
| Painkillers, NSAIDs (tablets, gels) | Pain in most conditions | Mixed evidence | Little evidence they treat carpal tunnel itself |
| Cortisone injection | Carpal tunnel | Good evidence (short term) | Benefit lasts months; may return |
| Cortisone injection | De Quervain's, trigger finger | Some evidence | Small, older trials |
| Carpal tunnel release | Worsening or unresponsive carpal tunnel | Little research | NHS and AAOS describe good outcomes; compared with injection, too uncertain to judge |
| Trigger finger release | Locked finger after other steps fail | Little research | Stiffness for months |
| Cortisone injection | Tennis elbow | Mixed evidence | One randomised trial found worse results at one year |
| PRP or blood injection | Tennis elbow | Good evidence of no meaningful benefit | Cost and risk without proven gain |
| Tennis elbow surgery | Pain lasting 6 to 12 months | Little research | AAOS reports 80 to 90% success; strength loss not uncommon |
