I am having various, mild physical chest pains which Kaiser thinks are sore chest muscles from excessive coughing. The coughing fits seem to be my involuntary failure to keep crumbs/ or spit out of my windpipe like I use too. I m 81 and mother developed a similar problem in her late 80s. A chiropractor suggested it may be the taking of statin for over 20 years, that might create muscle problems. So??
