kerr,

Yes, as most have said, if you have it covering a large portion of your skin then definitely go get a steroid shot.

Secondly, take some over the counter Claritin. It will produce antihistamine and will relieve a large portion of the itch for about 20 hours (24 hour tabs).

Third, I've found that Calagel just doesn't cut it, at least not for a long enough period personally. I prefer Benadryl gel, designed specifically for poison oak/ivy type itches. Works for about 4 hours on really bad itches.

Finally, it should be clearing up. BUT, if you take a really HOT shower or wrap the itchy spots with a very hot towel (and I mean hot, like right out of the microwave) you will induce a very large amount of histamine. Initially you will get about a 30 second incredible itching/tingling sensation from the release, but then you should be itch free for about 2-4 hours. I found this really helped before bed...

Good luck...
