I know that CS is rare, but I think I might have it.
I can't run more than 15 minutes without my calves becoming very tight. The tightness gets to the point where it is painful to run. Even when I stop during the run to stretch them out that does nothing. Then after the run the tightness goes away for a couple of hours. I have always struggled with calf injuries, but never like this. Massages, inserts, stretching, the stick, and rest do not seem to help.
If not CS, does anyone know what this could be then?
