I have little red bumps on my legs that have a hard white center when you pinch them. If I can get the hard white center out, the bumps go awayl I also have what has been diagnosed as scarabic caratosis all over my back that came up post mentapause. I have had them frozen off many times, but they come again. Now they are coming on my upper arms, upper legs, neck and stomach. Insurance does not cover their removal, says they are cosmetic. Both my parents had them, and now they are coming on both my daughters backs post menapausal. they itch all the time, very bad. Do you have any other diagnosis or advice? Forget it, I never give my credit card on line. Sorry .
