Grid/Net shaped rash
My boyfriend gets these net-shaped patches on his back once in a while, according to his mom it's been happening since he was a teen. What is it? It doesn't hurt or itch. He takes a medication called Modecate.

My husband woke up with the same type of rash this morning. Perfect diamond shaped hexagon pattern across the middle of his back. He's had it once before but the shapes were less defined last time. Haven't figured out how to post photos here yet...!
They are not raised or itchy -- just shapes
Photos of geometric grid-shaped rash below. My husband had this rash appear in May 2024 and May 2025
Made account for this. have odd geometric pattern on my back
I had this happen twice both times after eating alligator. It has to do with a sugar molecule from something, in my case that ate mammals..If AGS is suspected, avoid consuming mammalian meat, dairy products, or any thing containing alpha-gal. When I told people I broke out in a rash with squares, they didn't believe me. I think that has to do with the alligator connection.
