|Can anyone tell what a fast and easy way is to get rid of poison sumac/oak? i have a job interview next week and i need it gone ASAP!! I have had this rash/breakout since Sunday, doesn't itch anymore, and somehow its still spreading, and very bad too. The rash is covered on almot 35% of my body and i have been taking oatmeal baths and it doesn't seem to be doing anything. So if anyone can help, please leave a reply.
