Hello everyone, I haven't been on the site in a while. But I had to comment on this because. I have allergies all seasons. I drink a lot of herbal tea non caffeine. I also use a nasal spray and I have a humidifier in my bedroom that I use every night. Stay hydrated. I drink a capsule on vinegar with light tasting olive oil. Twice daily. It helps me with the inflammation and coughing. I hope this is helpful. Good night. Blessings

Steam, teas and and Zyrtec (cetirizine) give me a lot of relief.
If you're feeling adventurous, or just desperate, you could try a neti pot for rinsing your nose with saltwater. It helps by washing out the pollen, dust and other allergens that can stick to the inside of your nose, triggering repeat allergic reactions like sneezing.
Add a couple of drops of mouthwash to the neti pot to make the rinse more refreshing. It's nice to rinse your nose in the shower, where the steam helps you breathe better.
Good luck!

Depending on where you live, you may be encountering "super pollens" this year, so seasonal allergies may be worse than normal. I don't get seasonal allergies, but even I'm sneezing a lot this spring. Besides the meds everyone's already mentioned, wear a mask if you have to spend time outdoors working or doing yard work. You'll inhale a lot less pollen and other allergens which may help reduce symptoms. Indoors, a good air purifier can also help. Be sure you're using one with a certified HEPA filter for best results.

Begin taking local honey a couple months so it builds up in your system to ward off unwanted allergies.
Indoor time with air conditioning for filtered room air.
Taking showers, changing clothing and laundry clothes after being outside.
Sinus rinses.

Humidifiers help. Make sure the machines are cleaned of dust every week and put distilled water in them not tap water to reduce bacteria in air. I made calico cotton taped on air intake to catch some of the dust from going into machine. The store bought air conditioner filters also are not adequate. I cut thin cotton cloth or thin worn out towels and put against air conditioner intake coils and then put the commercial air filter over that to hold it in place. It condenses and causes some moisture in the air conditioner but doesnt seem to hurt anything but it sure does catch more dust and I don’t have to remove air conditioner as often for cleaning. Just wash cotton cloth in washer nd use over and over. Keep a few extras. Also dead insects laying about cause autoimmune response. I had some carpet Beatles make webs all over everything and there were des ones everywhere. A scientist told me from Texas A and M that the dead insects had to be cleaned up well as they could affect me systemically in my blood from breathing it in or skin absorption. I had to get husband to remove curtains and wash them. If I center touched the curtains myself, I got a rash. I live where grain fields are so we get invaded with thousands of carpet Beatles, Miller moths, grain weevils and the like every harvest. Once we got rid of every trace of dead insects my COPD and recurrent pneumonia and allergies went away.
