Rinse sinus with neti pot, shower and shampoo before sleep and frequently change your pillow case. These things get rid of pollen in your hair and what is on your skin that you can't even see. Pollen gets transferred from hair to pillowcase too. Was a game changer for me.

Clearing out the sinuses with saline for me before using Flonase has helped it be more affective. Nightly 24 hour allergy med plus sinus med for day time when needed. All combined seem to help me.

I actually invested in a vacuum and air filter system. It wasn't cheap but as a long time sever allergy sufferer, I was desperate to try anything. I used to take two prescription allergy meds and still wasnt finding relief. It was hands down the best, albeit expensive, purchase I ever made for such items. It's been going on 9 years I think at this point. It, along with remoing all the carpet, ( i still vacuum, not sweep the floors) made such an improvement in my life, I can't even remember the last time i had to take allergy pills or even had a sneeze attack. Unfortunately I do have lasting sinus damage and still suffer from the effects of that ie sinus infections, ear issues etc.

When I do any real yard work, I wear a mask.

I use a Netty bottle and rinse my sinuses, use Flonase, and a nasal inhaler called a Boom Boom Stick I got at Walgreens. It helps the allergies and the migraine attacks. Benadryl at night if needed
