I'm an idiot. I have some calendula salve around the house already and totally forgot to use it. The rash is very superficial and not large, but may as well take care of it.

I've been using Traumeel gel on the contusion (arnica and some other stuff). I had that already, and it's 25 miles in the wrong direction to the nearest place I can get some of the internal stuff. Not much rash where it's contused, since it was all under my shorts. It stung a little the first night, no problem after that. Rubbing it in gives it a little massage.

I forgot to make a nice comfrey root poultice, too. It's a wonder I can remember how to ride a bicycle... obviously I forgot the part about not crashing

Did a nice easy 32 this morning, that really helped break up the swelling. Like you said, increase the circulation.

And my bike got a bath, which it desperately needed, since I had to inspect it for damage.

Thanks all!
