At first I would get them on my arms and now I am getting them EVERY WHERE. I have noticed when I go out in the sun and come back home that they have sprouted up. They are SUPER itchy and very irritating. They look like a red strawberry patch on my neck. I am going to a doctor about it - however they do not last long only a couple of days and by the time I get into the doctor they are gone. Please let me know if you know what this is.
