Achilles tendinopathy, often referred to as Achilles tendonitis, is a common condition that causes pain, swelling, and stiffness in the back of the heel where the Achilles tendon connects the calf muscles to the heel bone. The tendon helps lift the heel off the ground when walking, running, or jumping. Overuse, sudden increases in activity, or tight calf muscles can irritate the tendon, leading to discomfort and difficulty with movement. This condition may develop gradually and can affect both athletes and non-athletes alike.
My approach to Achilles tendinopathy is to think of it less as an injury that needs rest and more as a “tendon that needs to be rebuilt.” In the early phase, I focus on calming things down enough to get you comfortable, but I don’t believe in shutting everything off completely. The tendon actually responds best to the right kind of load, so I use activity modification, supportive shoes or a heel lift if needed, and a gradual return to movement instead of complete rest. The goal is to reduce pain while keeping the tendon active so it doesn’t weaken further.
Once the pain starts to settle, the real work is slow, steady strengthening, building the calf and tendon back up so it can handle everyday stress again. Most people improve without surgery if they stay consistent with this process. Surgery is for the group who don’t get better after months of proper rehab or who have more advanced tendon damage. In those cases, the philosophy is simple: clean out and repair what’s damaged, but even then, surgery is only part of the solution, the real recovery still comes from rebuilding strength, control, and function through rehab afterward.

What Causes It
The Achilles tendon handles enormous loads — up to 7 times your body weight during running. When the cumulative load exceeds what the tendon can repair overnight, the fibers begin to break down. This is tendinopathy: not inflammation, but degeneration.
Common triggers: sudden increase in training volume or intensity, tight calf muscles, flat feet or overpronation, worn-out running shoes, or returning to activity too quickly after time off.
Types of Achilles Tendon Pain & What It Feels Like
Midportion tendinopathy is pain 2 to 6 cm above the heel, the part of the tendon that’s easiest to feel if you squeeze the cord in the middle. This is the most common form. It’s caused by repetitive overload that gradually degenerates the tendon fibers.
Insertional tendinopathy is pain right where the tendon attaches to the heel bone. It’s often accompanied by a bony spur (Haglund’s deformity which is sometimes called a “pump bump”). Tight shoes that rub the back of the heel make it worse. Treatment for insertional tendinopathy is slightly different because the tendon is attached at the painful spot, making some standard exercises (heel drops) more aggravating than helpful.
Morning stiffness and pain in the Achilles tendon that eases after 10 to 15 minutes of walking is the classic sign. Pain usually returns with prolonged activity or at the end of a long run. You may feel a thickened, nodular area in the middle of the tendon. Squeezing the tendon reproduces the pain exactly.
Imaging and clinical testing help confirm the diagnosis.
Treatment Options
Non-Surgical Care
Most patients improve with conservative care. Treatment typically includes:
- Eccentric exercises: Controlled calf-lowering exercises that strengthen the tendon and encourage healing
- Stretching: Regular calf stretches to improve flexibility
- Activity modification: Reducing or avoiding pain-producing activities like running or jumping
- Footwear modification: Supportive shoes or heel lifts to reduce tendon strain
- Ice therapy: Applying ice for 15–20 minutes, two to three times a day
- Anti-inflammatory medications: Short-term use of ibuprofen or naproxen to relieve pain
- Shockwave therapy: Used in chronic cases to stimulate healing
- Platelet-rich plasma (PRP) injections: are sometimes used for cases that haven’t responded to other conservative measures. Evidence is mixed, but some patients respond well.
Corticosteroid injections are generally avoided within the tendon because they increase the risk of rupture.
Surgical Care
Surgery is considered if symptoms persist after six to twelve months of structured rehabilitation. Options include:
- Tendon debridement: Removal of degenerated tissue and repair of the healthy tendon
- Calcaneal spur removal: For insertional tendinopathy with bone spurs
- Minimally invasive techniques: Such as percutaneous debridement or stripping of abnormal vessels, which may reduce recovery time
Postoperative care includes gradual rehabilitation with physical therapy to restore strength and flexibility.

Warning Sign: Is the Tendon About to Rupture?
Most Achilles ruptures don’t come out of nowhere, they happen in tendons that have been chronically degenerated. If you have Achilles tendon pain and hear or feel a sudden pop with severe weakness and inability to push off, this is a rupture and needs emergency evaluation. It won’t heal on its own.
Frequently Asked Questions (FAQ)
Q. How long until the pain goes away? Midportion tendinopathy typically takes 3 to 6 months of consistent eccentric exercise to resolve. Some patients see improvement at 6 to 8 weeks, but full resolution takes longer. Insertional tendinopathy often takes longer — up to 6 to 12 months.
Q. Can I still run while I treat this? Often yes, at a reduced load. The goal is to keep your fitness while the tendon recovers. A physical therapist can help you find the right level and progress it safely.
Q. Does a cortisone injection help? For the Achilles specifically, we use cortisone injections very cautiously. Injecting directly into a degenerated tendon carries a small but real risk of rupture. PRP or shockwave are safer alternatives.
Summary and Takeaway
Achilles tendinopathy is a common and often preventable source of heel and lower leg pain. Early recognition, rest, and structured rehabilitation are key to recovery. With consistent treatment and proper footwear, most people return to full activity without long-term limitations.
