Okay! Yes I just discovered the Therabreath stuff..I use the mouth wash, it's oxygenating. I need to get the toothpaste too because supposedly it's support to work. Sinus problems.. I don't think so. I have allergies so sometimes I'm congested but I can breathe fine right now and I don't think I've had a fever. Just a headache. I'm toughing it out at work right now. But I'll see what I can do. I go back to college next week so I just wanted to get rid of this so I can have a good time moving back in. Hm a numbing mouthwash may be what I need. I'll have to give my doc a call. Thanks Lynn!
