I’ve gotten it only on my torso and never any visible bumps but definitely an extreme itchiness. Not only from deep creek but also spending a couple hours in Willet’s tub which was around Womb temperature. I think it helps to take breaks between to let your skin dry out and expose yourself to some sunlight. The one treatment I’ve read that helps decrease the symptoms but doesn’t kill the bacteria is acetic acid, so I use apple cider vinegar and it definitely helps with the itchiness.
