I've had this since February. I recently started running again but then I attempted a cross country run and this was obviously too much for my tendons and now they're sore again. Have you got it on one foot or two? I got fed up with not running and interestingly road running seemed to help strengthen it but perhaps that was just coincidence! I know all the advice says rest but after 7 months, I was going crazy!
