19;5'5;185; i've never had any medical problems. For the past few months i've been tired all the time and I get headaches everyday. Within the last two weeks, ive noticed just one lymphnode (located right under my chin on the right) has been swollen. I have a few pinprick sized red dots on my right breast and chest all of a sudden and a hard pea sized knot in my left breast. Sometimes I have difficulty breathing and heart palpatations.
