I went through a couple of years of shots for my nasty sinus allergies and the shots really helped, but they seemed to bring on my asthma and increase my heart palpitations, especially after getting an injection.
Currently I am looking into SLIT, where instead of injecting the Allergen into the body, the patient does it at home using drops. You get a bottle of Allergen Drops in the mail, and you place a couple of drops under the tongue. I am waiting for the package to read it and see how much it costs and if it is covered by my insurance.
In fact, I am currently going doing Sublingual immunotherapy (SLIT) treatments at home, and, so far the experience has been good. At this point, I am very pleased!
Sublingual immunotherapy (SLIT) is supposed to be a lot safer than the shots (SCIT), although the science is still in it's infancy and there are more questions about SLIT than answers, at this time.
Besides the shots (SCIT), I've also had Acupuncture to treat my sinuses and asthma, and I've gone on a strict diet, and I am only taking one snort of Asthma Medication per day (Flovent 110).
I take one snort of Flonase per day in each nostril to keep my sinuses free and clear. It works. But, I also have to avoid the allergy triggers.
If I leave to go to a different area, let's say, on vacation, when I leave my allergies get better, but when I come back there is Hell to pay. I would guess that when you go to another area, you pick up a lot of different allergens and have, let's say, a mild reaction, but when you come back, the corabination of the allergens from the other place, plus the allergens back home, give a cumulative and much nastier reaction than normal!
