Hi, so 4 days ago my girlfriend and i got into a little fight and she just started punching me in my chest one after another this happened around 11am. i started work at 2 and still had no pains until maybe 7 or 8pm. im guessing its from all the movement from work. i also smoke marijuana for seizures and also cigarettes (i know thats bad for me) and every time i would cough, clear my throat, sneeze, or even try to get out of bed it would get more and more sore every time........ so my question is did i bruise my left lung, is it soft tissue damage, or could it be getting more worse since im still smoking???????????
