My husband over several years has encountered poison ivy frequently and has always taken him MONTHS to get rid of it. This latest encounter spread to his scrotum and groin. It had originally started over a week ago on his forearm, then spread to other arm, neck, hands and thighs. He states (because he is too embarassed to let me see) that this is the worst by far, his scrotum was enlarged, painful, itching, and hardened plus his groin had also swollen (which we now know was his lymphnodes). He saw 3 different doctors (he had been in the field for army training) and finally got the correct meds- oral steriods and zanfel cream. Being he has always reacted badly to PI, should I be worried he isn't doing enough? More meds? Frequent soaks? Also will this affect his fertilty?
