I wore lock up wrist splints for 4 years, on both of my wrist due to Carpel Tunnel. I had just bought another new pair, at the cost of $140.00, when I was diagnosed with Diabetes Insipidus. Miraculously, my carpel tunnel went away......My Neurologist thinks that now that my body is hydrated properly that my wrists are fine now....
I am out $140.00 for brand new braces, but no more carpel tunnel......
