Yesterday at work I began having a horrible pain in my lower chest. It was right under my breast area and it felt like a horrible gripping cramp all around that region. If I stood up straight and didn't move it was slightly less painful. as soon as I made any movement it began hurting again. Breathing became difficult and I also got a dull aching pain from my neck to my right shoulder.
I excused myself from work and went home. By that time the pain in the chest was not so bad but I continued having an aching shoulder through the rest of the night. Today when I woke up my chest area feels somewhat sore. I've had this once before and that was about 3 months ago(The first time I ate spicy Mexican food the day before and thought perhaps it was heartburn or something).
One more symptom I experience that doesn't seem to be associated with Angina is a build up of saliva. When I spit it out it's long and stringy.
I am overweight, but I've never had any heart problems. I don't have high blood pressure either. Is it possible for a nineteen year old to have Angina or is this possibly a stomach problem?
