Hi guys and gals , I recently noticed a lump under my skin , inside my chest , closer to my left breast than my right . You cant see it but you can definitely feel it . Its about the size of a pea , its sore and its starting to itch. I cant move it. I'm getting very worried. Has anybody else had this happen to them , if so what happened ?

Thank You

What we do instead of just panicking... is see a doctor. Let them determine if it's a cyst, inflamed lymph node, tumor, etc. None of that can be done on the internet.

Aren't you in college now? If so, you have a college infirmary.
If you are a senior in HS, you need to tell your parents.

(I had a lump as a teen that was not only benign, it went away on it's own, but that is not relevant to you or anyone else.)
