Re: Allergy testing negative but suffer all symptoms
Well, there could be a few things going on.
1) Did you take Claritin anytime within a few days of the test? Or any other antihistamines? That could cause a false negative.
2) It could be you are allergic to something not tested for. (Unless you have a furry pet not tested for, this one is less likely. Most people with ANY allergies will react to at least one of the common allergens, such as cat, dog, dust, mold, or your main local pollens.)
3) You may have non-allergic rhinitis, where your nose reacts to irritants rather than allergens. Possible irritants include pollution, smoke, perfume, or cleaning chemicals. The symptoms are the same, and the steroid nasal spray should still work, but antihistamines don't help.
4) GERD can actually cause sinus problems, too! At night, the acid can get high enough to irritate the sinuses. What are you doing to get that under control?
5) Whatever the causes(s) of your sinus problems, the deviated septum is probably making things worse. If you try lots of other treatments and none of them help, you might want to have surgery to repair it.
Also, have you ever tried a saline rinse for your sinuses? Regardless of why you have sinus problems, rinsing 1-2 times per day can help.
