Rickochet Haven't tried that but do break blisters for the Clorox. When I was in the Marines, my arm was so bloated I couldn't bend it, they didn't play and took steroid shots. Gone in 2 days--naturally, there was no downtime. Had steroid shots in the AF as well when the boots would not fit. As I aged, I seemed to be less vulnerable.
Good ole calamine helped some.
My dad told me he heard if you ingest something you are allergic to, the body will create a defense. He said he was in a world of hurt for a week after eating some. Never tried this.
