I Am a 19 year old female and I'm pretty healthy as far as weight and things go. I have been getting these really bad pains for about a month in both sides of my chest(feel deep) and under my armpit and a couple of times my right side of my body has gone numb. During these chest pains I get cold sweats and bad migraines, and sometimes nauseous. Sometimes my vision gets blurry and sometimes I'm very light headed Sometimes these chest pains last all day sometimes its just very frequently thru out the day. I'm just wondering what is causing this?
