I was diagnosed with GBS in the early 90's, which i got all of my mobility back except from the knee on down & wear AFOS on each leg. I started taking 300MG of Gabapentin for RLS, then noticed severe pain in the outer calve. My doctor raised it to 400MG for severe nerve damage. Well a month ago it has gotten so bad he increased it to 800MG. A couple of weeks ago, i started getting a rashes on my face & forearms along with itching that drives me crazy. So can i get these symptoms from the increase? Thank you...
