Doctor, I’ve been experiencing bumps that appear in the same spot on my chest. These bumps don’t fade or shrink; they stay the same size. When I try to pop them, they bleed and form scabs. After they heal, they leave dark spots, and then more bumps form in the same area, sometimes 3 or 4 at a time. Could this be a skin condition, infection, or something else? Am attaching pic for reference.
