回复：7岁男孩花粉过敏厉害，想给他做immunotherapy(allergy shot).有谁做过吗？

It's very hard to say. All my family have severe allergy problems: pollen, weed, dust etc. My hu*****and and I both are under allergy shot treatment for years. His result is good, but mine was bad, I even developed new allergy symptom such as Asthma and entended the allergy season. Even allergy doctor can't explain why. So I stop the treatment finally. I would be very careful and cautious to do this immunotherapy in so young age. Immune system is very complicated and mystious. It's better not to intrude it by outside force. Wait for couple years, it is possible that he might grow out of it.
