Kind of a gross/weird question but it has me perplexed
About 2 months ago or so, maybe a little less, me and Cailin were playing and all of a sudden she grabbed my right ear and pulled really hard on it. A few days later I noticed the crevice behind my ear (where the ear and my head meet) started getting irritated and crusty. I didn't think anything of it so I kind of just rubbed it off and forgot about it. Well about 2 weeks later, I noticed that it had spread and is now almost all the way around the back of my ear. It's also on the back of my earlobe. I wash it everyday hoping that it would get better but it hasn't, so I went and got some peroxide and have been dabbing it but it seems like I do that, then it crusts back over.
It's pretty gross, but more weird than anything. You can't see it but I know it's there. It's also red and it doesn't hurt unless I touch it. What could it be?
