This could be a handful of different things, but since you're not too worried right now, and getting healthcare is extra-tricky at the moment, have you first tried moisturizing in case it's just skin dryness, which it very well could be, especially this time of year? Like, if you use an oil or lotion for a few days (and maybe use a gentler soap to wash with if you were using anything harsh, like a deodorant soap), does it help, get worse, or stay the same?
Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has. - Margaret Mead
