Thanks everyone. It seems like it either has to do with the sensitivity of the skin or how the test is performed. How strange, DS has hypersensitive skin and you can gently rub your nail across his arm and it will turn into a red line for a while (DD would "write" on him when he was younger) but it doesn't hurt him at all. I am surprised to see how many people saying it hurt, I was starting to wonder if the woman burnt him, he also had red circles on his arms for a couple of days after the test.</end quote></div>
My doctor says I have a skin allergy called dermotographism. He literally wrote the word 'HELP' on my stomach with his fingernail (then called the entire staff in to see it because he thought it was funny). It sounds like your son has the same allergy. Maybe that's connected to why the sweat test was painful for the both of us but not for everyone...? It's a common factor, at least.
