They do get sore like a
zit, and sometimes I can squeeze them, in which they only sometimes react like a
zit. However, when I do that, it seems as though a day or two later, the lump hardens, and it takes weeks, if not months to go away.
Even more recently, I got a lump on the upper portion of my forehead (right side) that became large, and very sore. I never touched it because it was nothing like a pimple. It took about a week to reduce in size, then go away.
