Hello, from the summer somewhere on my chest red small spots appear on my chest, they do not itch, do not hurt and in a day or two disappear by themselves. They appear after physical contact with my girlfriend - usually after we slept together at night, even without having sex - until noon during the day. A dermatologist described it as a variegated lichen - I took two courses of treatment, but it didn't go away, I was also with an allergist - and his pills didn't help. Today I noticed that I have a neck. Ideas what it could be or some adequate dermatologist who will not diagnose me at a glance? M31
