My son is 5 years old. He was recently having horrible allergies and we had him tested. He is allergic to just about everything. He was in a constant state of allergic reaction (stuffy head, cough, wheezing.) He got to the point I thought I would have to take him to the emergency room. We started him on Singulair and zyrtec and a nebulizer as needed. We also started allergy injections. he's been on them about 3 months. We finally had an ENT look at him and we decided to have his adenoids removed. Right before the surgery he had pnuemonia, so he missed 2 weeks of injections. Then the week of surgery I didn't take him as he had enough going on. So in all he missed 3 weeks of injections. After the surgery it was amazing. He was breathing through his nose, sleeping with his mouth closed, not snoring, no cough, no stuffy nose. We kept him on the singulair and zyrtec. The week after the surgery, I took him to get his injections. That night he started that familiar cough. The following week I took him on Monday. Tuesday morning he started coughing. Wednesday I took him for his next shot. By Thursday night, the cough was really bad and he had a 101 fever. Friday morning his heart rate was very high, his cough was horrible, he was wheezing and breathing quickly, and he had a 100.6 fever. These are all things that were happening before the surgery. I'm beginning to think he's having a reaction to the injections. Can anyone confirm this? It is Friday, the 4th of July so I will not be able to ask his doctor for 3 days. If it gets worse, (the breathing) I'll have to take him to the emergency room. But in the meantime I was just wondering if anyone has had this experience or has information that may help my son.
