Bug bites, spider bites, the itching can drive one insane lol. Have to share: have tried cortisone, and all kinds of stuff that didn't help one iota. The one thing that did help was to put a spot of OraJel on it and it stopped immediately, and went away quicker than anything else. Last yr, I also used it for itch when I had shingles, which also worked. Amazing that simple toothache numbing stuff could work so well!
I've done the exact same thing with mild poison ivy. Works very well.
