Hi, I am a 29 yr old female. I noticed a pea-sized lump on the back of my neck on the right side where my hair line starts about a year ago. It doesn't hurt but my scalp does itch in that general area and had since I noticed the lump. For a few months now Ive had a burning sensation in my left armpit and in my chest next to my left armpit. Its almost all the time, as time goes on its more frequent. I've also noticed lately that Im constantly out of breath. If Im sitting on the floor and get up, Im immediately out of breath and get dizzy some of the time. I have no health insurance and everything i Google leads me to cancerous subjects.
