The pain is so bad i can t even move my neck right  <response>: Hi, I am sorry for the situation you are going through. The pain you are having behind your left shoulder blade which is being eased by Flexeril, it is muscular-skeletal also known as fibromyalgia. It is common for your age as is commonly occurring for ages 20 to 50. I advise to:- take anti-inflammatoryanalgesic medication orally-apply analgesic cream locally-apply warm clothing locally-schedule physio-therapy exercises to relieve the stiffness and pain-do exercises on regular basis Good positioning during sleep can also help.
