Hi yesterday I cleaned it an extremely dirt water trough in my horses' field, couldn't wash my hands properly- went to the toilet(not very clean, no hand wash facility )- few hours later started itching and noticed a lot of swelling around my vagina and anus, then broke out in an itchy rash on my face, back, top of my legs and waist. Last night I spent all night being violently sick- rash spreading this morning, eye where a have a big patch not focusing properly. Can you help?
