question: The muscles between my ribs are really very sore. Not all the time though. Just when I do certain movements, like getting up from a lying position, sneezing, coughing. My right side was sore, and now my left side is sore. It hurts too when I take deep breaths. The pain compares to the pain a persin feels when you have exercised too hard and your muscles ache the next day. I have been coughing quite a lot the last month...had bronchitis. How do I treat this?
