Activity changes
Keep moving, but change how much, how fast and on what surface while the tendon heals.
Achilles pain · Upper West Side
Pain at the back of the heel or up the tendon can stop running, walking and stairs. Dr. Rottenberg finds which part of the tendon is irritated and why, then treats it with a plan that can include MLS laser therapy, heel lifts, custom orthotics and a step-by-step strengthening program.

What it is
Achilles tendonitis, also called tendinopathy, is irritation and wear in the tendon that joins the calf to the heel. Pain a few inches above the heel and pain right where the tendon attaches to the bone behave differently and are treated differently.
It often follows a jump in activity, a change of shoes, hill or speed work, or tight calves. Walking long distances on city pavement adds up too.
How it is treated
Most Achilles problems get better without surgery. The first goal is to calm the pain: adjust activity rather than stop it, add heel lifts or orthotics, and use MLS laser therapy if it suits you. A patient review credits MLS laser with easing her Achilles pain in a few short sessions.
The second goal is to make the tendon stronger so it does not flare up again. That means a gradual loading and stretching program and a clear plan for returning to running or sport.
Your options
Most people need a combination of these, adjusted as the tendon settles.
Keep moving, but change how much, how fast and on what surface while the tendon heals.
Short in-office sessions that can reduce pain and inflammation, with no downtime.
Take strain off the tendon in everyday shoes and running shoes.
A gradual loading plan that makes the tendon more resilient.
Your own concentrated platelets, considered for long-standing tendon pain that has not healed.
A short period of protection for severe flare-ups.
Considered only when months of good care have not helped, or after a rupture.

Questions patients ask
Your own answer depends on an in-person exam. Call the office if your question is not here.
Call (212) 724-4457Not always. Many runners can keep running at a lower level while the tendon recovers. Sharp pain, limping or pain that worsens during a run means stop and get checked.
Mild cases often improve in a few weeks. Long-standing tendon pain can take several months of steady strengthening. Your plan will include checkpoints so you know you are on track.
MLS laser can reduce pain and inflammation for many people, which makes it easier to keep up with strengthening. It works best as part of a full plan, not on its own.
Steroid injections into the Achilles tendon are avoided because they can weaken it. For long-standing tendon pain, PRP (platelet-rich plasma) made from your own blood is an option Dr. Rottenberg can discuss.
A sudden pop, a feeling of being kicked at the back of the ankle, and trouble pushing off are warning signs. Call the office right away or go to urgent care.
