Delayed contact reaction?
My DD broke out in hives on both hands today right after finishing lunch. Started with two on one finger (looked like whitish welty mosquito bites) then the other hand, and two on wrist arm. Nothing unusual or new for lunch eats all the things she ate very frequently. She is PA/TNA. What I am wondering is we went to Gymboree playgroup today two things standout there...the soap in the bathroom had a spicy/fragrance and the gymbo stamp they use on their hands. The only thing is the hives didn't start till 2 hours later/after Gymboree (and we washed up and changed clothes when we got home before eating). The hives lasted about 15 minutes old ones disappearing, new ones starting- so I got out the benedryl which resolved them completely and gave her a bath.
Has anyone ever had a contact or soap reaction delayed for around 2 hours? Has anyone ever had an ingestion reaction of just hives on hands- no other symptoms? Just hoping to get some ideas/advice. Thanks!
