So I finally went to the doctor to see about the crazy arm rashes I’ve been getting, and it sounds like I have polymorphous light eruption.
It sounds super cool, but it basically means I’m allergic/sensitive to UV light. It’s a delayed reaction where you’re fine when you’re out in the sun but after the sun exposure occurs, then your immune system starts going “OH SHIT” and reacts to it, causing rough-looking rashes/blisters and lots and lots of itching.
So, you know, no big deal.
I’m just out in the sun for four hours to get my 15-mile walk in every day.

And no, sunscreen doesn’t prevent it. I’ll either have to wear long sleeves or suffer the itch/redness. But for some people it seems to “flare” at the beginning of spring/summer when there’s more sun, but if they let it blister up and then heal, it “hardens” the skin against it until next spring/summer. We’ve been having a lot of cloudy/rainy days this week and my rash is almost gone, so maybe my arms will have healed enough by the time it gets super sunny again. WHO KNOWS, IT’S AN ADVENTURE.
Edit: well it’s mid-July now and the “eruptions” have definitely diminished a lot. So I either don’t have this at all and my arms were just being spazzes, or, like some people, I flared up at the first major spring exposures to sunlight and then “got used to it.” Odd news.
