question: Hello, My name is Dottie, 47 yr female, 5'2, 220 lbs with Multiple Sclerosis (RRM) and A Mitral valve prolapse.1 week ago  this coming Thursday I went to my doc for pain in left bottom of my ribs when I breathe, cough and sneezing  was horrible. The week before I had a horrible sinus infection that settled in my chest and had alot of coughing espicially at night. So I thought maybe I had a pulled muscle from coughing so much.He said I have Pleurisy and put me 875 mg amoxicillian 2 times a day. The pain during the day is easing off but at night it hurts  a lot to try to lie flat on my back and on my side feels like there is a pocket sticking out of my lower ribs the  really hurts  when putting pressure on it. Now I have a stinging going around to my back on the left side. Is this part of Pleurisy too? No exrays were taken just   a routine exam listening to my chest and blood sample where he d determined I had an infection . Should I go back and suggest exrays?I still have 2 days worth of meds left. Thank you for your time.
