I have another post about this topic but I'm not even sure if it's poison ivy. It does itch but not a Normal poison ivy itch. More like a dry painful itch. Feels like a million little bee stings. I have had it about a week. There is cortisone10 on it right now that's why it's so shiny. I just can't deal with it anymore! It hurts! I sleep like crap. If it's not better by Monday im going to have to go to the dr. Would taking a Benadryl tablet help at this point? And can I take Benadryl with the cream on?
