Dermatologists have a cream for everything. Once in a while I have a horrible itch breakout on the top of my feat; so bad I'll scratch it bloody. In this case, the one pound tub he prescribed does work. Works well for chiggers too.
In the case of the fungus, prednisone would have been a mistake, but I nonetheless sometimes feel I am a target for a form of alternative medicine. Why didn't _I_ get a prednisone pill instead of a tub of corticosteroid lard?
As for chiggers: in college I got a serious case of chiggers from a romantic blanket evening in the Texas desert. We two were apparently the only mammals within miles as every chigger available mobilized to fulfill its Darwinian destiny. Next morning I awoke up with a maddening itch everywhere (and I do mean _everywhere_) that lasted until the chiggers died (~3 days IIRC). Best treatment was to take as hot a shower as possible [The only thing better than sex is steaming hot water on chigger bites - it's like the Scratch of God]. Rest 30 minutes and repeat. I've heard a hair dryer works too. Thanks to your recommendation I'll keep the tub of steroid cream around just in case.
I think my dad also takes it in much lower doses for asthma.
But, it has horrible affects both long and short term.
Google "Hells itch"; it's worse than chiggers. Had it twice. First time I needed a steroid injection. Second time 20 years later I knew what it was and heavily dosed myself with Benadryl for 2 days.
