Late last year, our 9yo daughter had blood allergy testing. We were scheduled for her to come back in for prick tests, then an under the skin testing yesterday (to determine which shots she'd need). As per the instructions, we put Litocaine on both her upper arms and wrapped them with Seran Wrap (for the injections). Before any "official" testing, 3 controls were put on the underside of her left arm, near her wrist: histamine, glycerine, and albuterol saline. After 10 minutes, she had no histamine reaction. The nurse looked perplexed, but repeated the test with a different batch of histamine. After 10 minutes, still no reaction. The nurse consulted another allergy nurse, 2 ENTs, and a PA. The only thing they all could agree on is that they'd never seen that happen before. She has elevated IGE's (880) and is always covered in a wierd
hive-like rash, which would seem to me that she is having a reaction to something.
After determining that no further testing could be done, the nurse took off the Seran Wrap and wiped off the Litocaine with a piece of plain gauze. My daughter started screaming that it burned. Her arm turned beet red and the prickly hives started popping up (we were seriously watching it happen). She complained the rest of the day about her arms burning and they were constantly red. This morning they are less red, but the prickly rash is still there. I'm thinking maybe her allergies are more contact / chemical? But wouldn't even those require a histamine reaction? Any suggestions or thoughts would be greatly appreciated. We have a call in to an immunologist, but don't expect to hear from her until Monday.
