I am 25, fit, and active. Every couple of weeks I get achy pain in my calves that lasts for a couple of days. I get minor relief by stretching a bit, but the pain is worse at night and when I am sitting. Working out, particularly biking, provides relief during excersize, but the pain returns once completed.
I also have a congenital heart defect, not sure if it could be playing a role.
Any ideas on the culprit?
