<s>[INST] Hi, I have been to the gym without warming and using the over head pull down bar the nest day I was a little sore on my neck shoulders and arms then I got a stiff kind of feeling in my neck and now my neck shoulder and arm and fingers have kind of like quick spasm pain or if I am moving my arm around on rest the pain eases up I think its nerve damage, thanks [/INST] It could be cervical spondylosis due to excessive weight lifting.I suggest you go to an orthopaedic surgeon and get an MRI. while you are awaiting that try a muscle relaxant by the name of Flexon 500mg 3-4 times a day.And please don't work out till you have a diagnosis </s>
