Well I have something strange I can't figure it out what is this. I don't know how since when I have it but only yesterday I noticed small bumps behind my both ears. I'm clueless if they appeared only at one ear then they spread on another but I thought that is nothing to worry about that it could be harsh skin or pimples, now I'm sure it neither of them. They are growing in number very quickly as today these bumps are significantly more than yesterday. Their location is all over my ears and even on my neck and back hair, mostly on the back of my ears. I don't really feel them as they itch only a little bit but when I touch them they start to hurt. I am afraid that they could start itch more and more or to cause me pains. Could it be? And also, could they spread more and more? Will they stop spreading on my body at certain moment? I don't know how to describe them so everyone could understand me. They are really small like pimples as I said and have a pinky color, anyway those who ever heard of this or maybe had it will understand me. I didn't used any lotions or creams yet since I know that it can make it worse if I use something wrong, and I don't know what medication should I use to treat it. The possible things that could cause it is that I switched to a new, unknown for me shampoo recently. And also, yesterday I went to pool. Of course I've been to pool before but I never had something similar, so I just cannot say whether of them caused its apparition. Can someone help? I would love to hear at least any hints that could probably help me. Thanks in advance.
