So far from what I have exp the drs have been very helpful...once I got to the right ones. I'm goin in next Monday for my SGB and pray pray pray. Yesterday my one good arm started symtoms and I woke up this am with part of my arm numb and fire. Sorry typing bad my pinky andring fingers r numb need to believe its not spreading to my only useful arm. Need all of u thank u
