I hate the taste of Flonase as it post nasal drips down...ugh, nasty spitting it out. When my eyes swell shut, Allegra helps, but the chronic sinusitis is a different "entity" & can be barometric pressure or temperature or humidity related. Also, mold, mildew & dust affect breathing. Pollen or dander are not the only culprits. There are also chemical sensitivities to consider. Bleach cleans well but sets my nose & throat aflame. A saline nasal flush or netti pot can help clear out the gunk & that is my 1st "go to" dealing with congestion. If it's a barometric pressure issue though, the only thing to help that is when the storms finally blow out to sea & the sun shines to dry everything up. Sometimes sinuses are affected by mere temperature fluctuations, too. My nose becomes a leaky faucet at 45 degrees & colder. Benedryl may be good for allergies, but it'll also give you a good night's sleep, so taking it during the day, while driving or operating machinery is not a good idea. If your nose is clogged at night, though, even with taking Benedryl, it might be a dust mite issue. Washing bedding with hot water & trying to address dust mites could help. Also, if you have ductwork with forced air, they probably need professional cleaning. Change your air filters at least every 30 days. To reduce what pollen, sawdust or dander I track in, my outer clothes stop right at the laundry room, coats get shaken outside then hung up & jeans or hoodies go right into the washer & I get a shower to get any allergens off of me. Hair or hats will harbor a surprising amount of pollen. Does not matter if I had a shower that morning, I do not skip the pollen & dust removing shower. Keep your house & especially bedroom & bed as pollen free, dander free or dust free as possible. If you have a ceiling fan in your bedroom, dust off the tops of the fan blades, trust me, they're dusty up there. With seasonal asthma, allergies, barometric sinusitis & teen years sick with chronic bronchitis & a few bouts with pneumonia in my life, I can attest to what has helped me, so I hope some of these ideas can help y'all as well. Being stuff up is just not a good way to be!
