Thanks Hiram. He’s been camping many times and he’s never gotten it before. That doesn’t mean anything, but if he was ultra-sensitive to it, I would expect he would have gotten it as some point. He is autistic and he splits his time between his computer, his television, and the pool (except for the occasional family outing to the lake). If it is poison ivy, then your explanation of a dog might explain, as his mother does have a lab (although they don’t really live in a wooded area). Either way, I appreciate your well reasoned response to my questions. There’s another gentleman who has hijacked this thread that has pushed poison ivy as well. I’ve decided to let a doc decide in the morning.
The doc is a very wise choice .... I wish you well!
It is poison ivy and it looks like he is already scratching and spreading it. Get a poison ivy scrub to get rid of the irritant and then get a calamine mix that has a topical anesthetic in it to relieve the itching so it can heal.
I understand your suspicions of your ex, the difficulty with a child who cannot express himself but common sense dictates that a very unusual (if you aren’t familiar with poison ivy) thing like these blistered spots you reserve judgment and take the child to a doctor even if it’s expensive and also perhaps heed the remarks of several people on this thread who said poison ivy rather than dismissing them out of hand. You really did make yourself look foolish by jumping to rather drastic assumptions about your ex. Accusations like that are very damaging and should be made not first, but last after other explanations have been exhausted.
I got to say, the one mark on the arm looks like a spider bite to me.
