I know none of you are doctors but i cant seem to find any info on this so i thought id ask to see if anyone else has experienced this. for some time now, it seems i get these random itchy red bumps. id like to think it's an allergic reaction but they seem to appear out of nowhere. like ill be at work or in my room not eating for some time and then out of nowhere i find myself being itchy on my arm somewhere and it's one of these bumps. the closest i came with was ringworm but i saw those pics and they're nasty looking and mine dont look anything like that. if i leave them alone without scratching they seem to go away after a while. it's a raised bump in a perfect circle and gets red around the area.i have attached pics so you can see what they look like. i only get these 1 at a time never in groups. if you look closely you can see the circle raised shape.
