I have had severe spasms in my rib cage after a fall on ice and a concussion. The spasms are rather hard to relax. Now I am experiencing a tingling, electric feeling in my rib cages on both sides simultaneously. When i tilt my head forward, sitting, or driving, a small tingling, not hurting, sensation starts and lasts about two seconds as it transcends downward. Tonight, driving home for 100 miles, I experienced the feeling making its way to my side and even into my arms. There is no pain, and little discomfort but it seems to be intensifying.
