Help! Im scared! Im 48 yr old female, have had benign palpitations for 15+ yrs, but have NEVER had chest pain/discomfort before. Very overweight-high bp, otherwise healthy. Had the H1N1 flu in mid-November. Was left with terrible cough, treated w/ antibiotics. Noticed few weeks into Dec that when I would walk a distance, that my chest would burn-like when you breathe in cold cold air. Well, its cold-cold here, so I figured that was it. It continued. The cough went away. Saw my reg Dr on 12/21..
