I've been getting these sores on my right arm. They start out like bug bites but they stay forever. As soon as i get rid of one another comes on the lower right forearm. I clean them with peroxide,alchol to dry them out, anti-bacterial cremes,cover with band-aids,But nothing =I do seems to work, What could be causing them? I've already checked the different body products i've been using in case of an allergy to them. Could it be caused by milk? Please give me any info. you can about what can cause these sores. Thank You
