I have always had a small, raised, symmetrical mole on the right side of my chin. It had a hair growing out of it that I consistently plucked. About 2 weeks ago I noticed a small, shiny whiteish bump on the mole. Over the last couple of days the mole has gotten bigger though it has stayed symmetrical and is still slightly smaller than a pencil eraser. It also stings to touch and doesn’t grow hair. I’m conscious it could be an inflamed zit or a cyst or a trapped hair follicle but am scared
