Achilles Tendinopathy: What a Foot Surgeon Recommends Before Anything Else

By Christopher R.D. Menke, DPM, FACFAS | Double Board-Certified, Foot Surgery & Rearfoot/Ankle Reconstruction | American Board of Foot & Ankle Surgery

Two patients came into my office last month with pain in the back of the heel. Each one described it differently at first. One pointed to a spot low on the tendon, right where it meets the bone, and said the pain was sharp and exact. Another pointed higher, along the middle of the tendon itself, and said the pain was harder to pinpoint, more of an ache that spread. The exam told me two different stories, and the treatment for each one is not the same.

Two Different Conditions, One Painful Tendon

Achilles tendon pain in adults usually falls into one of two categories, and getting this distinction right changes everything about treatment.

What Is Mid-Portion Achilles Tendinopathy?

Mid-portion tendinopathy is damage to the body of the Achilles tendon, typically two to six centimeters above where it attaches to the heel bone. This section of tendon sits in what is sometimes called the watershed zone, an area with the lowest blood supply along the entire tendon. Poor blood flow means poor healing, which is why this form of tendon pain tends to become chronic rather than resolve on its own.

What Is Insertional Achilles Tendinopathy?

Insertional tendinopathy affects the tendon fibers exactly where they attach to the calcaneus, the heel bone. This area is more degenerative in nature, with tendon fibers gradually disrupted and occasionally pulling away from the bone over time.

What Is Fusiform Swelling?

Fusiform swelling is a firm, palpable nodule that develops within the body of the Achilles tendon. It typically signals a small tear that the tendon is attempting to repair on its own, and it is usually the exact spot where the patient feels the most pain.

How to Tell the Two Apart

Patients with mid-portion tendinopathy often describe more generalized pain, spreading across a wider area of the tendon, with one especially tender spot where fusiform swelling can sometimes be felt. Patients with insertional tendinopathy tend to describe the opposite. The pain is sharp, specific, and easy to point to with a single finger, right where the tendon meets the prominent bone at the back of the heel.

On exam, the tissue over the mid-portion of the tendon is supple, though firm when a nodule is present. The tissue at the insertion is hard, sitting directly against bone with very little soft tissue in between.

What Doesn't Work

Before addressing what helps, it is worth addressing two habits that tend to make Achilles tendon pain worse instead of better.

Walking barefoot or in flat, flexible shoes puts the tendon under maximum tension with every step. Aggressive stretching is the other common mistake. Patients often reach for it instinctively, but repeated feedback across years of practice tells the same story: stretching a chronic, already-struggling tendon typically increases pain rather than resolving it. Most Achilles tendon pain seen in the office is chronic by the time a patient comes in, and by that stage the tendon has stopped responding to attempts at self-repair. Overstretching adds load to tissue that needs less of it, not more.

What Actually Works: The Conservative Treatment Sequence

The First Thing to Change

Before any product or procedure, the first adjustment is footwear. Transitioning out of flat shoes and into a shoe with a slightly elevated heel reduces tension on the Achilles tendon immediately. This is the one situation where a raised heel is the recommended direction, opposite of most other footwear guidance given for foot and ankle conditions.

Conservative Care for Mid-Portion Tendinopathy

Kinesiology taping is typically the first treatment tried for mid-portion tendinopathy, and for anatomical reasons it tends to work unusually well in this location. The tissue over the Achilles tendon is thin, sitting close to the tendon itself, so the tape is able to grip the tissue directly and function like a superficial splint. Kinesiology tape is also dynamic rather than rigid, which allows it to move with the curved contours of the ankle and heel in a way that traditional medical tape cannot.

Topical medications, including topical CBD, are a reasonable second option, though they cannot be used at the same time as kinesiology tape since the skin needs to be dry for the tape to hold. A supportive shoe paired with an orthotic is typically added next, both to stabilize the foot and to provide a mild, tolerable lift at the heel. An oral steroid course can help when tissue inflammation is significant. Injections directly into the body of the tendon are avoided in this population, since they raise the risk of further tendon damage and rupture.

For tendons that do not respond to these initial measures, the next step is laser therapy, shockwave therapy, or both, generally combined with a period in a walking boot to limit motion and reduce activity. If that combination does not produce enough improvement, platelet-rich plasma injection paired with shockwave therapy and boot immobilization is the next option before surgery becomes part of the conversation.

Conservative Care for Insertional Tendinopathy

The same general sequence applies to insertional tendinopathy, though the details shift to match the anatomy. Kinesiology taping is still a first-line option, applied differently to account for the more distal, posterior location at the heel. A gel compression sleeve is also useful here, particularly for patients whose pain is worse at rest or at night, or for older patients who have lost some of the natural soft tissue cushioning at the back of the heel.

Topical medication and an oral steroid course remain reasonable options. Orthotics can help stabilize the foot and elevate the heel, though the response varies more from patient to patient in this location and needs to be monitored closely, since a small number of patients experience more shoe irritation with an orthotic in place rather than less. Injections are not used at the bony insertion itself, both because of the added risk of tissue damage and because an injection directly against bone in this area would be significantly painful.

Laser and shockwave therapy remain reasonable next steps if initial measures are not enough. Platelet-rich plasma injection is used less often for insertional tendinopathy than for mid-portion cases, though it remains an option before surgery.

A Note on Pace

How quickly a patient moves through this sequence depends on the individual. Weekly follow-up allows for course correction based on how a patient is responding, how compliant they have been with the plan, and how their pain is trending. Some patients prefer to move slowly through conservative options. Others, particularly active individuals or those training for a specific event, prefer a faster, more aggressive combination of treatments from the start. Either approach is reasonable, as long as the direction is toward improvement.

When Surgery Becomes Part of the Conversation

If conservative treatment does not resolve the pain, surgery is a reasonable next step rather than a failure of everything that came before it. Mid-portion surgery generally focuses on repairing the damaged section of tendon. Insertional surgery is more often involved, frequently requiring removal of a posterior calcaneal bone spur along with debridement and repair of the tendon itself, which typically means a longer recovery than mid-portion surgery.

When to See a Foot and Ankle Specialist

Kinesiology tape, orthotics, a gel compression sleeve, heel lifts, and a compression ankle sleeve are reasonable starting points for individuals managing Achilles tendon pain conservatively at home. For many people, these measures alone provide meaningful relief. Evaluation by a foot and ankle specialist is recommended when pain persists, fails to improve, or worsens despite consistent use of these conservative measures.

Separately, sudden sharp pain at the back of the heel, especially during push-off, along with a palpable gap in the tendon or an inability to point the foot downward, can indicate an acute Achilles tendon rupture and warrants prompt medical evaluation.

What to Do Next

Start with footwear. Transition out of flat, flexible shoes and stop any aggressive stretching routine. From there, kinesiology tape, a supportive orthotic, and a gel compression sleeve are reasonable first steps depending on where the pain is located and whether it is worse during activity or at rest.

Frequently Asked Questions

What is the difference between mid-portion and insertional Achilles tendinopathy?

Mid-portion tendinopathy affects the body of the tendon in an area with poor blood supply and tends to be tear-related. Insertional tendinopathy affects the tendon fibers where they attach to the heel bone and tends to be more degenerative in nature.

Should I stretch my Achilles tendon if it hurts?

Aggressive stretching often makes chronic Achilles tendon pain worse rather than better. Reducing tension through supportive footwear and taping is typically more effective in this situation.

Can Achilles tendinopathy be treated without surgery?

Yes. Most cases respond to a sequence of conservative measures including kinesiology taping, supportive footwear, orthotics, and in some cases laser or shockwave therapy, with surgery reserved for cases that do not improve.

How long does conservative treatment take to work?

Response time varies by individual. Weekly follow-up allows adjustments based on pain levels, compliance, and progress, with some patients improving faster through a more aggressive combination of treatments.

Is a raised heel shoe good or bad for Achilles pain?

For Achilles tendinopathy specifically, a shoe with a slightly elevated heel reduces tension on the tendon and is one of the few situations where heel elevation is recommended.

What does fusiform swelling mean?

Fusiform swelling is a firm nodule felt within the body of the Achilles tendon, usually indicating a small tear the tendon is attempting to repair, and it often marks the area of greatest tenderness.
