You twisted, lifted, or trained a little too hard, and now a tendon in your shoulder, elbow, knee, or heel aches every time you move it. The good news: tendonitis is one of the most treatable overuse injuries there is, and most people get better without injections or surgery.
Here is the part that frustrates people most. Tendons heal slowly, so the right plan is less about a quick fix and more about doing a few simple things consistently. Below is what the evidence actually supports, step by step.
How do you treat tendonitis at home?
For most cases, the first-line treatment is conservative care you can start today. The classic approach is R.I.C.E. (rest, ice, compression, elevation) paired with over-the-counter pain relievers, according to the Mayo Clinic. The goal in the first days is simple: calm the pain and swelling so the tendon can settle down.
That usually looks like easing off the activity that triggered it, wrapping or elevating the area, and using an over-the-counter NSAID such as ibuprofen or naproxen sodium for pain. Rest does not mean total shutdown for weeks. It means backing off the aggravating movement while you let the tendon recover.
- Rest the painful tendon and avoid the movement that flares it
- Ice acute, sudden injuries to bring down inflammation
- Compress with a wrap and elevate the area when you can
- Use an OTC NSAID (ibuprofen, naproxen sodium) for pain as directed on the label
Should you use ice or heat for tendonitis?
This is one of the most-searched tendonitis questions, and the answer depends on how new the injury is. Ice is recommended for sudden, acute tendon injuries because it helps reduce inflammation, while heat may be the better choice for chronic, overuse tendonitis because it increases blood flow and can relieve pain, per the Mayo Clinic.
A practical rule of thumb: if the pain came on suddenly and the area feels hot or swollen, reach for ice. If it is a long-standing, nagging ache from repetitive use, gentle heat before activity may feel better.
What exercises help tendonitis heal?
Once the sharp pain settles, the most important step is loading the tendon correctly, not avoiding it forever. The first-line physical therapy for tendinopathy is an eccentric exercise program, where you slowly lengthen the muscle under load, such as lowering into a weighted heel raise. These programs are commonly done with daily sessions for about 12 weeks, according to peer-reviewed evidence published through NIH/PMC.
Eccentric work is especially well studied for the Achilles. For mid-substance (noninsertional) Achilles tendonitis, eccentric exercises produce a positive effect in roughly 60% to 90% of patients, per the American Academy of Orthopaedic Surgeons. The key is consistency: this is slow, gradual rebuilding, ideally guided by a physical therapist so you load the tendon enough to stimulate healing without overdoing it.
How long does tendonitis take to heal?
Patience is part of the treatment. Most overuse tendinopathies recover within 3 to 6 months with conservative care, according to NIH/PMC. Acute, milder cases often calm down faster, while stubborn, long-standing ones sit at the longer end of that range.
If you have stuck with rest, activity changes, and a real eccentric program for several weeks and you are not improving at all, that is a signal to get evaluated rather than to simply push harder.
What if home treatment is not enough?
When conservative care fails, there are second-line and advanced options, though they are not the starting point. The Mayo Clinic lists extracorporeal shock wave therapy (ESWT) and platelet-rich plasma (PRP) injections among these, with surgery reserved for cases that fail several months of treatment or for an actual tendon tear. Shock wave therapy as a second-line option has effectiveness similar to an eccentric strengthening program, and the two can be combined, per NIH/PMC.
Corticosteroid (cortisone) injections deserve a careful note. A 2010 systematic review of randomized trials in The Lancet found that steroid injections cut pain in the short term, but the benefit reversed at 6 and 12 months, with worse long-term outcomes than no injection for tennis elbow (lateral epicondylalgia). That is a big reason injections are no longer first-line. Just as important, cortisone injected directly into the Achilles tendon is not recommended because it can cause the tendon to rupture, and the same caution applies to the biceps and patellar tendons, according to the AAOS.
When should you see a doctor for tendonitis?
Most tendonitis is safe to manage at home, but some situations need professional evaluation. See a clinician if your pain is severe, does not improve after a few weeks of self-care, keeps coming back, or limits everyday activities.
Get prompt care if you felt or heard a sudden pop, cannot bear weight or move the joint normally, or see significant swelling, redness, and warmth, which can suggest a tear or infection. A clinician can confirm the diagnosis, sometimes with ultrasound, and tailor a plan, including supervised physical therapy. If you want a convenient starting point, a clinician-overseen service like Nolla can help you figure out whether your symptoms warrant in-person evaluation.
