Raychel,
I have to report the opposite effect. I have had some type of sinus pain, head-aches, and joint paint for at least the last 18 months strait. I'm on day 5, this time, without smoking and I have no headache, no sinus pain, and very minimal joint pain. What I figure must be occuring is some type of bio-chemical imbalances and then rebalancing, unless maybe your blood pressure is up. Check with your doctor ASAP just to be safe. Difficult to say since we seem to be experiencing exactly the opposite effect. My doctor agreed with me that my smoking was a very likely cause of the sinus troubles I have experienced. In any case I wish you well and don't fool around. See the Doc! Saline mist works for me followed by hot compress across my face. I'm not taking OTC pain relievers anymore either.
