I have recently been using this book:
I have found this to be really useful in managing by left sided lateral calf, left hamstring and left sided lower back pain.
I have had this pain in the lateral calf for around 3-4 years. It used to occur during tough endurance sessions on the track (when i went through a long to short intensive tempo type routine (dont ask!) ), and it got to the point where recently I cant even walk without getting it.
I’ve tried everthing which only seemed to make it worse - 2 sets of orthotics, stretching, yoga, strengthening, rolfing, massage, resting etc etc and the only thing that seems to help is trigger point therapy.
I know its early days, and it may all come back when I resume working out, I just thought it worth a mention if John or anybody else wanted to give it a try. I found out trigger points in my gluteus minimus are potentially the cause of my pain. Now I have to work out what it is about me or my training which is creating the trigger points.
