Norsk, I read with GREAT interest your reply to a person who had lower back pain on coughing, and your response that it was likely due to a inflamatory disease. I am most interested in your position, and it sounds logical. By the way, my Dad is a retired Lt.Col, USMC (Donald R. "Slim" Harris) who also flew the F4 Phantom in Vietnam. (Thanks for your service to the USA!!) Anyway, I hope you get theis note and that you can respond. Sincerely, J.W. Harris
