For the past 2 weeks I've been having this itch around my anus. The itchiness subside after an hour or two of being itchy, and then becoming itchy again some time after that, 12 hours or even a day. I tried feeling my anus, and felt some tender rashes around it. It is the first time this happened to me, and coincidentally, it happened right about the same time I started sneezing and getting alergic to something. Is it an alergic response? Because I had alergies the same as I am experiencing right now in the past years and no itchy anus has been experienced then.
