I have a problem with the Achilles tendon area directly behind my left ankle bone. I run 5 miles per day and begin to experience pain intermittently at about 2 to 3 miles into my run. The pain goes away after several hours following a run. I like to run at least 7 miles per day but when I increase my mileage to 7 the tenderness is more pronounced and I have to apply ice. Stretching the Achilles provides no relief. I can do toe raises and it does not hurt. I stopped running for one week but the problem persists. What's up Doc?
Crispin, it sounds like you have an achilles tendon tendonitis, but the muscle that is irritiated is probably the Soleus muscle rather than the Gastrocs. You can tell if your achilles hurts when you stetch your Achilles tendon with a bent knee rather than a straight knee. Most runners overlook this achilles stretch, and I would highly recommend it. Continue to use ics and NSAID's under the direction of your physician. One otehr consideration for you if this stretch doe not help, is to look into orthotics. Extrensic rear foot posting (a wedge that lift the inner side of your heel) might help a lot. You can also do heel raises with your knee bent Crispin, in order to directly recruit the soleus. Some cross training might be in order as well - something like roller blading out doors, or slide board indoors.
Best of luck to you.
