I have suffered from this since I was child. Mine is brought on by allergic reactions, especially in Spring and Fall. Some years pass with little problem. This year, Im reacting to the trees getting their leaves in, atm.
I take aspirin to reduce inflamation. Vitamins C & D as well, diuring this time. I have suffered from bronchitis since I was a child, when the sinusitis persists for very long, which results in losing sleep, and subsequently time from work.
To have it all year, check for a mold source in your home, or some other continuously present factor in the general environment of where you live and work/study. If that is not present, consider the health professional options mentioned on page one.
Vicks Vap-o-rub around the nose can help you breathe through your nose, and relieve the continuous chapping in that area from the constant nose blowing - it will sting sharply at first, but that will pass in a minute or so.
Best wishes! I feel your pain, literally!
P.S. People acquire and relieve themselves of allergies throughout their life, so if you were never allergic to something before, that doesnt mean you cant be now.
