It starts as a nuisance. Lifting a kettle, turning a doorknob, shaking someone’s hand — a sharp, specific point of pain on the bony bump at the outside of the elbow. Six weeks later it is still there, and you have quietly started using the other arm for everything.
That is lateral epicondylitis if it is the outside of the elbow (tennis elbow), medial epicondylitis if it is the inside (golfer’s elbow). The same story plays out at the Achilles, the patellar tendon under the kneecap, and the rotator cuff.
There is one fact about these conditions that changes what you should buy, and most pages selling you something will not mention it.
It is probably not inflammation
The -itis suffix means inflammation, and it is largely a historical mistake. When tissue is taken from a chronic tennis or golfer’s elbow and examined, what turns up is usually degenerative change in the collagen — disorganised fibres, abnormal blood vessel growth — rather than the inflammatory cell population the name implies. This is why the field increasingly says tendinopathy rather than tendonitis.
That single fact explains a lot of frustration. It is why the ibuprofen that helped for a week stopped helping. It is why the brace at the chemist’s did not resolve it. And it is why anyone promising you that an anti-inflammatory of any kind — ours included — will repair the tendon is telling you something the tissue does not support.
There is a nuance worth keeping: early-stage and recently aggravated tendons do show a reactive, irritable phase, and the tissue around the tendon can genuinely be inflamed and sore. So pain relief is not pointless. It is just not the same thing as repair, and it helps to be clear which one you are buying.
What actually fixes it
I would rather you know this than buy something on a misunderstanding, so plainly:
- Progressive loading. Eccentric work and heavy slow resistance, ideally programmed by a physiotherapist, is the intervention with the strongest track record. It remodels the tendon. It is also slow — three to six months is normal — and it asks you to load a thing that hurts, which is why people abandon it.
- Managing the load that caused it. Grip size, technique, desk setup, sudden increases in training volume. If the input does not change, the tendon keeps losing.
- Time. Unsatisfying, but most of these do settle. The job is to stay functional and keep loading sensibly while that happens.
One thing worth knowing before you ask for it: corticosteroid injection reliably reduces pain in the short term, but across the trials it tends to fare worse than exercise at the one-year mark. It is a legitimate tool for getting through a specific bad patch. It is not the fix it feels like at week two.
Nothing you rub on your elbow will reorganise collagen. If you have had this for months, or you are losing grip strength, see a physiotherapist — that is the treatment path, and delaying it is the most common way these become year-long problems.
Where a topical genuinely reaches
Here is where tendon problems differ from most of what we write about, and it works in your favour.
We are usually sceptical of topicals, because the structures behind most chronic pain sit centimetres deep. We make that argument bluntly on our hip osteoarthritis page: a hip joint sits 5–10cm below the skin, and no cream is reaching it.
The common extensor tendon is not like that. Put a finger on the outside of your elbow and you are touching the bony landmark the tendon attaches to. There is skin, a little fat, and then the tendon origin — millimetres, not centimetres. Our roll-on uses a nano-emulsion that penetrates approximately 4–6mm into tissue, and for this particular anatomy that is genuinely within range. The same holds for the wrist, the Achilles, and the patellar tendon.
What that means honestly: a topical can plausibly act on the pain and the reactive irritation around the tendon. It is not remodelling the collagen — your loading programme is doing that. For getting through the working day, for the ache after a session, and for staying able to do the rehab that actually fixes it, that is a reasonable thing to want.

No trial has tested CBD in chronic tennis or golfer’s elbow. It is too specific a condition to have attracted one, and I am not going to dress up adjacent research as if it were the real thing. Two studies are genuinely relevant, and both are worth reading accurately.
Tendon surgery, human, randomised. A placebo-controlled, double-blinded trial in 99 patients undergoing arthroscopic rotator cuff repair (Alaia 2022, American Journal of Sports Medicine) gave CBD or placebo for 14 days after surgery. On day 1 the CBD group reported significantly lower pain (VAS 4.4 vs 5.7) and were significantly more satisfied with their pain control on days 1 and 2. By day 7 and day 14 there was no difference between the groups, and opioid use was not reduced. Liver function tests were unchanged.
Read that for what it is: a Level 1 trial finding a real but short-lived analgesic effect around a tendon, with a clean safety profile. It used a buccal tablet, not a topical, and it was acute post-surgical pain rather than a chronic tendinopathy. It is encouraging. It is not proof that a roll-on fixes your elbow.
Tendon healing, animal. In a rat Achilles repair model (Stauch 2021, same journal), tendons from animals given CBD were no weaker and no less stiff than controls. It is a null result, and that is precisely the point — the authors concluded that cannabinoids do not appear to adversely affect Achilles tendon healing. If you are mid-rehab and worried about slowing a repair, that is the study you want.
For the underlying mechanism work, our CBD and inflammation page covers what is actually established, and Pramhas 2023 in knee osteoarthritis is the closest thing to trial evidence in a surface joint.
If it is more than one tendon
There is a pattern worth catching. If you are getting tendon pain in several places — both elbows, then a shoulder, then an Achilles — or if it comes with morning stiffness that lasts beyond half an hour, that is not a series of overuse injuries. That can be an inflammatory arthritis announcing itself, and enthesitis (inflammation where tendon meets bone) is a hallmark of psoriatic arthritis and ankylosing spondylitis specifically.
That is worth a GP conversation rather than another tube of gel. It is also the situation a transdermal patch is built for: systemic rather than one spot, a steady level for 24 hours, and still working when you wake up. It adds no NSAID load, which matters if you are already on one — see CBD and NSAIDs.

- Get a loading programme. This is the part that actually changes the tendon. Everything else is support.
- Change the input. Grip, technique, volume, desk. Otherwise you are rehabbing against a live cause.
- Use a topical on the tender point so you can work and sleep and keep doing the rehab.
- Give it months, not weeks. Judging a tendon at three weeks is how people conclude nothing works.
- If it is spreading to other tendons, ask about the systemic picture rather than treating each one separately.
Frequently asked questions
How long does tennis elbow take to settle?
Longer than anyone wants. Most cases improve over three to six months with sensible loading, and a minority run past a year. The trajectory matters more than any single week — if you are gradually tolerating more load, it is working even when it still hurts.
Should I rest it completely?
Generally no. Complete rest tends to leave you with a tendon that hurts just as much and is now weaker. The aim is to reduce the provoking load while continuing to load the tendon deliberately, which is exactly what a physiotherapist programmes.
Does the roll-on sting or smell?
It is cooling rather than hot — menthol and arnica — and it dries without residue, so it goes on under a sleeve or before work without announcing itself.
Will it show up on a drug test?
No. Both the roll-on and the patch are THC-free, and every batch is third-party tested with a published certificate of analysis. If you are tested in or out of competition, that is the specification you need.
