Chemical Burns

Yeah I did something stupid, so its like the coldest days we have had in our area. I fired up the hot tub for some relaxation in the 20 degree nights. Well I was a bit over exuberant with the chlorine and now I'm suffering for it. I Don't know if any one else has any experience with the whole hot tub thing but I found out if you put in too many chemicals you end up with little tiny bug bite like blister bumps everywhere. they itch they burn they suck.

I have like ten of them in various places, I'm not happy
