Poison ivy hits my husband

Last week of Tuesday, my husband started feeling itchy. First he thought it was cause by the chemicals he used at work or the new TIDE laundry detergent i used to wash our bed sheets and clothes. So then we didn`t really expect that it was the poson ivy. So then i changed our sheets and rewash again his clothes(haha it`s kinda funny). He didn`t bother him that day until the next days come his body started to get itchy. We`ll, i scratch everynight, everyday and as soon he gets home from work. Then his feet started to swell and i so much worried. I told him go to hospital last friday but he didn`t like it so we waited Saturday but the Medical Center was close till Monday. We headed then right away to the pharmacy and get some stuff for his feet and itchiness. We bought some ointment, lotion and powder. Still didn`t work and still swelling very bad. Then, yesterday he finally went to the doctor and gave him some medications... Hopefully it will get better as soon as possible... So guys, watch out for this plants they are really dangerous and poisonous...
