In reply to kmackenzie: it could be scar tissue, uve given conflicting evidence tho, is it between the tendons or on the tendon? im a sports massuer by the way.
if its scar tissue it could possibly be broken down with massage, would sting a bit though
i'd go to a good local sports therapist, gp's are as much use as tits on a bull.
get it checked asap, u dont want to mess ur season up this early in the year.
