I have a rash that seemed to be getting everywhere on my body, except it is not all at the same time. It is white when the skin is stretched, and it is mainly coming either when i itch or it may cause at itch. It is also coming as big red bumps, before you stretch it and see the white skin, much like a bug bite. I know it is not a bug bite, because it is winter,and i have not been to any camp grounds, where there might be bugs. I do not know what this is, so since you are a doctor, please help me.
