I was diagnosed this disorder abut 3 years ago. Initially my symptoms presented as a more serious disorder as the peripheral nerve in my left arm and hand had been destroyed by the disorder. It grew back about two years ago and now I am left with this disorder all over my entire body which according to my neurologist is an unusual presentation. I am currently on a reduced dose of cymbalta as the usual dose affected my thinking. I find that at any dose it will work providing you live in a geographical area where the barometric pressure remains above 1005 and is rising. If it gets beyond 1040 bp then 60 mg of Cymbalta will work to the degree where I was able to snow shoe about two miles without symptoms. When the pressure falls I prefer to do as little as possible. Has anyone else had this experience with barometric pressure and Cymbalta.
