I have been having upper back pain for about 2 months now. One month ago I had horrible pain and went to an urgent care facility. They diagnosed me with chest and back spasms. They did a chest x Ray and everything was normal. My pain is brought on by certain movements. They occur while driving or riding in a vehicle, laying on a pillow with my head tilted, and certain arm movements. The pain lasts about 30 seconds to a minute and is helped by pushing my shoulders back and taking a deep breath. I don't feel any knots when I get these and there is no muscle soreness before or after the pain. The pain is more of a nerve pain that is felt clear through into the chest, right around the bra line. It also radiates beneath my right breast. Could this really be spasms? This thing really got worse after stretching painting my walls. Help!!!
