last week i developed a scab on my eyebrow, at first i thought it was a zit and so i shrugged it off as something that will heal soon. But as the week went on it began to get bigger and bigger (the scab) and now it is the size of a penny and i am getting the same thing on the sides of my chin (scabs). They all seen to appear out of no where and they are starting to scare me! please help?
