i have poison sumac on my face. i was on my period while I had the poison sumac on my face and I guess from inserting tampons it has now spread to my vagina and inside my vagina. It is the weekend so I can't get to the doctor just yet. The itch down there is 20 times worse than the itch on my face. I am absolutely misserable. It is so bad it is keeping me up at night. Please help, what can I do to stop the terrible itch and discomfort that I'm in?
