Can I add a photo? Won't paste. I have big round circles on my arms. Dark red raised rings. Big ones seem to grow attached smaller ones. Some as big as an inch or two. Clear normal skin in the center. Some are half circles or s's. At first I thought it was ringworm but doctor told me he thought it was auto immune. Then I went to the lab and tested for auto immune and it said I don't have it.. I've treated them with steroids- and at first every kind of anti fungal. Nothing has fazed it. Started with one on the top of my hand. I noticed one day after I swatted a fly off that was biting me there. Then it changes shapes from circle to s shaped going different ways. It doesn't itch much. I've had for a year and a half and its covering both arms and shoulders and many growing in size. Do you have any idea what it could be? Also want to mention I have had extreme fatigue for a few years.
