From last couple of months I had been experiencing muscle spasm in my right side of upper back . Initially it seemed that be a normal spasm but later on due to frequent attacks over that part , I was not been able to sit ; all I wanted was to lie on my back to get relaxed . Have done LS spine , back x-rays , and other tests which were all normal . I used nervemax and myospasm tablets from last 7days ; a little relief I felt but the problem still exists.
