Cyndi,
Perhaps a good chiropractor could help you.
For maintenance, with allergy/sinus issues I have gotten relief taking Oreganol Oil daily, 5 drops under the tongue (or you can get gelcaps - the oil taste a little strong, takes some getting used to) and Oregomax herb caps - 2 a day before bed. Also Breath-ease by Dr. Grossman helps keep nasal passages clear (a nasal gel, you put a small amount in each nostril).
Here are some links, to show you what the products look like. Not sure if these are the best prices. I just googled them. We usually find the Oregano products at The Vitamin Shop stores. I think we ordered Breath-ease online.

And this book is really helpful - all about the benefits of Oregano.

A compress over the eyes and sinuses helps too. Breathing steam and sleeping with a humidifier can help too. And for immediate relief Tylenol Sinus has generally worked pretty well. Lately I try to stay away from OTC meds but sometimes for immediate relief, they are a great help. But with the mention of your jaw and neck, a visit to the chiropractor seems worth a try, could be tension related. Hope some of this is helpful.
Heavenly Father,
Please help Cyndi find relief for this pain. In know it can be debilitating. Touch her neck and jaw with healing and help her to find the source of this and the right remedy. In Jesus' name I pray, Amen.
