Hello, not so long ago I've noticed strange red dots on my chest back and stomach, only on these parts of my body, nowhere else. I don't have any kind of pain nor itch skin or something like that. They aren't raised off the skin and they size is between a really small dot to a diameter of a usual pen or pencil. I didn't go yet to my doctor since they do not disturb me at all, I don't feel them as I said recently, but I will get an appointment if I won't get any answers here and they won't disappear. Surely their apparition isn't a normal thing so I won't leave it so. I also don't know what caused them. I didn't go to pool, nor any forest trips in the last few months. The only thing I can remember is that I went to a different city with my family and we slept in hotel less than a month ago. I didn't change my diet or at least to try a new kind of food, so their apparition is a really mysterious thing to me. I don't know what they are even though I already made a research on the internet so hopefully someone here can help me.
