I think i have a bad chest cold or the beginnings of pneumonia and I Have been runnings a bit of a fever. I also was up all night with my heart beating out of my chest is this common with these conditions usually i sleep verry well never a problem i do toss and turn a bit but nothing to keep me awake like that. I was having what seemed like i was having trouble breathing i have had that before with a chest cold, but will that contribute to the fast heart beat? I know i was feeling like complete crap all yesterday and last night just looking for some answers please help?????????????????????????????????????????????? ??????????????????????
