To whom it may concern.
I have a female friend who wishs to remain aynonomus. She spent four days last week camping down near the springs and came home with the same red bumps under her skin. I saw her yesterday.
I too have had this hot spring rash in former years and lemon juice was the cure for me. At first the lemon juice hurts like an ant bite but then goes away. After @ 24 hours almost all of the rash was gone.
As for the cure for others I suggest everyone follow Forest Service rules and do not camp 4 days in a row.
Have a Happy Thansgiving !
