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?
