My 7 year old has red puffy fingertips on both hands. And on both middle fingers there is a little white dot (kinda looks like a blister). Has anyone ever seen any thing like this?
He first showed them to me last night and tonight he complained they were stinging.
At first I thought maybe just a allergic reation to something, but now I'm wondering if it could be severe enough for a doctor visit.

My little brother once got a puffy red fingertip on his hand, with a white blister-like thing, and it was a wasp sting.

It wasn't on all his hands, just the one, but he complained it hurt a lot.

In any case, if his hands begin to swell badly or he complains of severe pain, I would take him to the doctors.

We gave my brother Benadryl, but it's hard to tell over the internet what exactly is wrong with your son's hands.

If you have any doubts about his well being, take him to the doctor!
