i'm concern with my health and i'm a young teen girl. i have some symptoms that are concerning me that aren't normal.
so 2 days ago around 11 o'clock i started to have pain like something stabbing me right below my chest on my left and it close by my lungs. i havent ate so i'm pretty much hungry. before i go to my next class i have lunch so i ate a decent lunch which made my stomache calm down alittle but still in like pain that doesn't bother me. next thing i know i go to choir and i sing but the pain gets worse and i start to not breath and be in more pain. i put my fingers on where is and it makes less painful. i drink some water and didn't help. after choir i sit down for about 30 mins. everytime i took breather i feel a sting.. every since 2 days ago everytime i sing the pain comes back. but when i dont sing at night around 5-8 i feel chest pain. before i had chest pain but i would ignore it but now its hurts more and i'm afraid to sing and faint. i checked on sympton checker results and i've got a result that said collapsed lung (pneumothorax). i read about it but i've also have joint pains behind my left knee when i dance alot or laying down. i do eat the 3 or 2 times a day. drink enough water. i'm concerned about this. another to add is when i dance atleast for 3 hours, of course included breaks. i realize i get bruises either my legs or arms. when i'm outside in the cold my knee does hurt but bruises are shown. okay so basically there is alot things that mention but its been almost more then year of the burises and pain on my leg and now it's gone worse where i have chest pain and pain under my chest. can you pretty please give me the best advice and what i might have? you can even ask questions to see more in depths of what i specific i might have.
