answer:Are the bumps perfectly round? How large are they? I had cysts in my leg from an accident and it had an itchy crawly feeling from the inside. Did you slam that area in the past? Like black and blue bang. I still have some of the cysts, but they rarely bother me now. It took a couple of years. The skin might be dry, plus you might have some small cysts. They could be completely unrelated, but having the cysts might draw your attention to the area, and then once you touch it it gets the dry itch going on the skin too. That happens on my back. I don’t have cysts on my back, but if something starts a scratch then I can start to get itchy all over my back. I’m assuming it’s not skin tags since you say it’s under your skin. Did you ask a doctor?
