I thought that I was the only one who was like this. I actually didn’t even know that this was a symptom, but it explains why I hibernate each February while my allergies go crazy.
I do immunotherapy, and it has helped me reduce the medication that I have to take during the allergy season. I had mild asthma as a kid with no allergies, but when I was about 19 or so, I developed pretty severe allergies to pretty much everything. My allergist told me that the only things I didn’t respond to for the skin testing were cockroaches and mold. So I guess I could live in a cave, or maybe take between 2 and 4 medicines daily. Or I could get some shots and see how it works. For me, it’s a world of difference. My asthma is under better control and I tend to get sick less often in general. I’ve been doing it for about 2 years now.
Just a thought: you may not be seeing symptoms of your SO’s allergies if she is taking antihistamines like benedryl. The problem is that a lot of antihistamines make you sleepy. One of the main reasons I wanted to try shots is because the nasal sprays didn’t help my breathing, and antihistamines usually make me loopy (except fexofenidine).
However, to answer your question, yes, it doesn’t work for everyone. I’m lucky that I have good insurance that pays for everything, so it was worth a try. If I had to pay for each shot, I would have been less willing to try it, especially because it take can a rather long time to get any positive result. In my case, I started feeling a difference after about 6 months of weekly shots.
