My wife has constant year-round allergies. It seems like she has attacks that come in waves and then subside and then it happens again, but they are always bothering her. Been to many doctors ,been tested. Nobody can find anything that she’s allergic to. seem like it happened after she got over Covid, she is miserable. I don’t know how to help her. every medicine prescription or over-the-counter hasn’t worked to relieve her symptoms. If anyone has any advice on how I can help her, I would appreciate it.
