Hi doctor,I was in a car crash monday last week. Since I was discharged from hospital I ve been finding it hard to deal with coughing. I had quite a high speed crash into a tree so i suffered a broken collarbone, fractured left pubas part of my pelvis, very bad whiplash and bruising from the seatbelt. I m a smoker, so from time to time, after i eat or drink I may have to cough up some phelgm and I m finding that when i cough i get really sharp pains in the pelvic region. Just was curious was there any way i could cough easier
