about a week or so ago i got sick and felt like i had a fever and a bad cough, runny nose and all that jazz. i took medicine and over about 3-4 days i started to feel better but my cough still didn't improve. as time went on it seemed i was hurting myself coughing under and around my right shoulder blade area. this being because i would constantly cover my mouth and the cough was pretty bad, wheezing and all. its been about a week, maybe longer since and still my back hurts. it hurts when i lay a certain way or put too much pressure on it laying down. it hurts when i laugh, blow my nose, sneeze, move a certain way, breath in deeply et cetera. i went to the doctor worried because my mother had a problem with a blood clot in her lungs before and they told me because of my age and the fact i wasn't on birth control it doesn't seem likely. they said it seemed as though i pulled a muscle. but the pain seems to be getting more severe, not better. also, it seems to hurt under my right breast a bit as well when i take deep breaths and that... im not sure if its just feeling this way because im not letting it heal since i need to move around a lot and i keep coughing up flem or if i really need to get it checked out... any help would be greatly appreciated. thank you
