thanks for your question,
decompression of the median nerve
at your wrist will help with the pain and numbness
that you are experiencing from your carpal tunnel syndrome
but if you have weakness in your thumbs this may not recover. you can also get compression of the ulna nerve at the elbow causing weakness and numbness in yor hand, it differs from carpal tunnel syndrome as it is usually on the little finger side not the thumb side of your hand. nerve root compression
secondary to a disc prolapse
if your are experiencing shooting pains, weakness and/or numbness in your legs is a good indication for surgery to decompress the nerves.
