Nana - I acquired a couple new allergies this year too. Grass - notorious because of high pollen counts across the country. I've started my shots for that, so maybe next year, when I get built up on my dose, I won't have a problem with that again.
Then there was the albuterol rescue inhaler debacle. I had taken puffs for pulmonary function testing at the allergist's office with no problem. When I tried a single puff for a chest congestion problem I ended up in the ER with high blood pressure and very high heart rate. I'm waiting for a call from the allergist, but her nurse calls it an allergy. (I call it an acquired sensitivity, but who cares about the label.)
Bumpercar - The syringe is pretty much the same idea as the NeilMed sinus wash bottle. Of course they want you to use their very expensive salt and soda packets. My ENT gave me a "kit" after sinus surgery, and I love it. I just lean over the kitchen sink. It washes much better than the sprays, including aerosols, and I've tried a bunch. The sprays are fine for a quick hydrating rinse. Netipot doesn't have any pressure, so I wasn't thrilled with it. If you have really nasty infection ask the doc about adding a surfactant to help bust up the bugs' hold on the sinus walls. A few drops of baby shampoo should do the trick.
