I also get it really bad and have scars from the nasty stuff. The worst case I got years ago during December when I started hacking on a vine to mount a treestand with protective Carharts coveralls on. I figured it was dormit at that time of winter....WRONG
Aside from going to the Doc and getting a shot, I’m with you guys and the bleach as the best thing to help dry it up.
Bath with Clorox (as much as you can bare) or as I do, first shower with soap and rinse then squirt and rub in Clorox in affected areas and rinse again. If you already have it scratch raw, the Clorox will burn, but it helps to dry it up. It's also tuff to bare breathing in during showering (it'll open your lungs), but I'd rather endure a few seconds or minutes off pain the agonizing itch for days on end.
As a preventive measure, I frequently wash with Clorox year round if in the woods or know I come in contact with it. There some in the woods around the edge of my yard that I sometimes get into while mowing and the very first thing I do is when done is head for the shower and Clorox.
The way I apply it is pour it from the bleach container into an empty dish soap squeeze bottle and dispense it that way. As said, it's in the shower stall year round, and used it yesterday after mowing and again today's shower before work. It helps a lot, although it's good to use old bath towels after showering, cause it will stain them if you’re not complete rinse good.
