Hi,
Your symptoms seem to be of nerve compression. Compression of nerves in the spine due to bulging or protruding disks, bone spurs or other reasons may lead to muscle pain, numbness and weakness. Please go for MRI of the spine and consult a neurologist for the diagnosis. MRI of the arm and leg may be required after the neurologist evaluation. Decompression of nerves by surgery and physiotherapy may help in relieving your symptoms. Hope this helps you. Take care and regards!
hi...all I can suggest is trying one of the links that you see highlighted in BLUE just below you're question...click on you're post or on ARCHIVES to see more info.
you could also try the PAIN MANAGEMENT COMMUNITY there are many good suggestions there, I know one fellow RED931 if you look up his bio or PM him he is also going thr similar problems with his shoulder.
good luck
