The first spot appeared on my arm, and it was itchy (not ringworm). The second appeared about an inch above that, but it was not itchy. The third is on my leg. They are somewhat hard and tender to the touch. I've dealt with acne/pimples before, and this is not a pimple. I also don't believe it to be an ingrown hair, as the initial bumps were on my forearm where there is very little hair. Each incident has left a raised scar.
