I have heard of other people getting it after viral infections. And I haven't found anyone who really had an easy time getting rid of it. Some people swear by the steroid nasal spray, but I'm so reluctant to do it. An equal amount of people had bad side effects from it. I still didn't try Friar's Balsam yet. Been dragging my feet on ordering it. It's an herbal tincture that you're supposed to steam with. I heard it works, but I guess I've been hoping I wouldn't have to order it. A friend told me that her doc said to just have alot of vitamin C and D and lots of fresh air. Well, I've had alot of C and D for months, it's not working. Being out when I can, sometimes the air helps alittle, but it comes back.
