I don't think carpal tunnel syndrome explains all your symptoms either. Carpel tunnel is a type of neuropathy but it's probably part of another neurological problem. I hope the doc finds out more after these new tests. Let us know what you find out.
Actually, carpal tunnel is a quite common nerve entrapment, of the median nerve in the carpal tunnel at the wrist to be precise. It's usually not associated with other neurological problems, as it is a mechanical, local problem, easily corrected by a relatively small procedure where you open the carpal tunnel...
This will only explain the tintling or numb sensation in your fingertips, typically occurring at night, but also during the day...
Your right and I probably didn't say it the best way. It is a neuropathy but an isolated neuropathy that doesn't involve other body parts. I just find it odd that Jeremy has similiar symptoms in hands and feet but only carpel tunnel syndrome was diagnosed in his arms/hands. With his other symptoms like loss of balance and pains in his head, it sounds like a bigger neurological disease that may give similiar symptoms in his arms/hands like carpal tunnel syndrome. With more testing, they may make a better diagnosis. The neurologist probably diagnosed carpel tunnel syndrome for now with the evidence he had from testing so far. Or it could be carpel tunnel syndrome along with another neurological problem yet to be diagnosed.
