I ve had chronic dry cough for three weeks pain moved around from my chest to my lower back. I went to emergency and they said I have asthma. I m taking Albuterol, five puffs every hour with very little results. When I cough my head hurts and my lower back hurts. My left ear is hearing a throbbing sound and I have limited lung capacity as I get winded from climbing one flight of stairs. I had the first series of meningitis vaccine about three weeks ago. But I am not have those symptoms for it. Any suggestions?
