What Would Be Like To Be Poisoned? I Was Going

What would be like to be poisoned? I was going through a time that my lower legs were aching painfully. Then I found some relief by bathing. While bathing it was such an unbelievable sensation in my legs. Like pain itching and relieved some by staying in the hot water for a long time while I used the wash rag to rub / itch my legs below the knee. I am considering the possibilities, but would like some input to help me come to a conclusion.
