A Rash That Spreads When I Itch It :/

[imananomaly]

Hi,

I recently got a itchy spot on my upper leg or it may have been a bite im not 100% sure but whenever I itch it there becomes a red rash and it gets bigger and more red everytime I itch it, has anyone had this or know what it might be?

my dermatologist calls this the scratch/ itch/ scratch cycle. The result can sometimes be urticaria as a histamine response. This seems to be what you’re describing ie hives.

If it is, you might find topical zinc oxide (sudocreme, some mineral sunblocks) soothing. If I remember correctly, it delays histamine release.
