Migrating burning skin pain

I had a Dr appt the other day and forgot to mention a minor irritation that has gone on for several years. I seem to get a minor sunburn like feeling on parts of my body that moves around, usually it will be on my thigh or hip, then move to back and sides of chest, occassionaly part of my scalp. Pain is very minor but I am very aware of my clothes rubbing on sensitive sunburned like skin. No rash or discoloring. I looked it up on line and others report the same issue but I saw no answers. I assume because the problem is minor no research has ever gone into it. Has anyone ever dealt with this.
