I thought I had pulled a chest muscle. I noticed a small lump
on my right clavicle bone in
the front right at your neck, a few weeks later. Now the lump has gotten bigger, it is sore, and when I take a deep breath it hurts. My question is, should I get this checked to make sure its not some type of lump that needs to be biopsied. I have had some breast concerns too in the past month. Clear discharge, which was checked, no blood was found.
