I have been exposed to poison ivy, oak and whatever else is unknown to me in the back yard garden full of trees of many kinds. Four days ago I started feeling body ache, diarrhea, and yesterday I was feeling the itchiness in inside parts of my legs and under my feet. I thought the diarrhea was because I drank some kind of juice or tea or fiber nutrients such as multigrain rise, Ezequial cereal, or other so I stoped drinking juices and consuming such nutrients. Last night I had fever and I could not sleep, so I decided to research in the internet about this poison ivy staff and I found info on how to treat it with apple cyder vineger in water and a good cold-warm shower. I was having a lot of cramping in my legs, which I thought it was because I walked so much. I also took 2 allergy tablets of antihystamine and after a while I felt as sleep. Fever is gone, as far as I feel, but the diarrhea persists. What can I do to treat it without going to the hospital?
