I am not sure what I got into. My face iches and is red and swollen all over it started last night and there isn't any blistering Which I had expected since I spent the whole day out doing yard work yesterday. I thought this was some kind of poison but the absence of blisters make me think it is something else. What ever it is takeing two benadryl didnt help at all.The rash iches but when I touch it it actually hurts a little like a sunburn may feel and it is swollen and raised. there are splotches that are redder than others and the bumps are not uniform. My face is also hot to the touch. Does anyone have any ideas?
