Every once in a while, I get these zits on my nose or forehead that are extremely sore and hurt all the time. However, when I press on them or scratch them, I get a headache that can last for a couple of minutes or a couple of hours. Sometimes I'll get a headache if they're hurting more than normal. They have become more frequent lately and right now, I have one on my nose that is healing and 4 between my eyebrows that are very sore and are not helping my headaches any. The medications I'm using for acne are Proactiv and Minocycline (pill). Why are they doing this?
