2 weeks ago I was reaching across the table and my back spazzed out (right side), from the buttocks up. I did the usual remedies; heat, cold, pain meds, inflam meds, stretching. It's better (still a slight twinge in said area). yesterday I woke up with a very heavy feeling in my chest which got progressively worst during the day and today. It feels as if I was hit in the chest by something (not someone except maybe HEman (master of the universe). Also today it has migrated to my upper back, shoulders and when I lift my arms it's uncomfortable. If I take a deep breathe it's also uncomfortable.
