question: I am recovering from a fairly serious cellulitis infection for which I was hospitalized.  When I was running fever I felt alot of tightness in my chest.  No more fever, but I still feel the tightness even while resting.  My heart seems to beat rather strongly when I move around.  I have mild asthma and take medicine for that so my breathing is fine.My question is: is it normal to feel this when fighting a severe infection?
