The Achilles tendon is a tendon in the back of the heal. It can get inflamed or torn. Most times resting the tendon with occasional stretching will alleviate the pain. If the tendon is completely torn immediate surgery is indicated. If there is mild tearing or tendonosis this may be treated with PRP or TENEX procedure.
Retrocalcaneal bursitis is bursa inflammation to the back of the foot. This can be treated, though cautiously, with steroid injections so as not to cause of an achilles rupture.
These joints can be treated with steroid injections (also referred to as cortisone injections) under ultrasound or fluroscopic guidance.
This is a tendon that begins in the calf and terminates under the foot. Tearing can be associated with flat foot.
