I recently had a nerve conduction tests done which should nerve compression on my C5 and C6. I had the nerve study done believing I had carpel tunnel syndrome (symptoms included arm pain, finger numbness, wrist pain, hand weakness). I was once diagnosed with headaches, neck pain, arm pain and De Quervain's tenosynovitis - could these have been misdiagnoses and actually the pain, headaches, arm pain, wrist pain, and hand weakness been a result of the beginnings on C5 and C6 nerve compression and osteoarthritis? Any assistance and reference materials regarding this issue would be greatly appreciated. Thank you.
