All those symptoms that I had, my neuropathy symptoms are so bad right now and I am just nervous that they are not going to go away. My physical therapist who I saw yesterday says, I am just having a reaction and everything squared up right now and I am going to be okay he says, he promises me but I guess, I am just nervous because these symptoms are not gonna go away.
