perhaps it is time to consult a neurosurgeon....who will do your carpal tunnel? that doc actually might be worth a try for your leg issue.....i dont understand her description of the issue....i know exactly (only too well) where the nerve goes....what over use is she talking about? and if it is being impinged, by what ? and do you need "body" work, ie massage of some sort, etc?
make sure your work station is fine tuned for YOU, you legs shouldnt be hanging on the edge of the chair, as someone else pointed out...good luck
