I ve had a respiratory problem for about 2 months. My PCP has prescribed theraflu the first visit. It helped for a little bit. Then an inhaler with a serious. Two weeks later, I tried a steroid - two weeks later, problem and coughing getting worse, PCP perscribed a strong antibiotic and chest x-Ray. Lungs are clear. Tonight, I have extreme pain in my shoulder socket and ribs. All could be related to severe coughing, which has subsided. What should I do?
