I believe I have sinusitis. I was given antibiotic to take if I felt it didn't clear up. I didn't take it, but became sick again 2 weeks later.. It really doesn't feel like a sinus infection because my mucous is clear rather than yellow or green. However, this time all the teeth on the right side of my mouth are being affected. I went to the dentist who took xrays and said it isn't my teeth, but may be a blocked salivary gland. I've had it before on the left side, but it did not involve my teeth. Cold makes it feel better and hot foods make it worse. It can come on and last for a couple of hours. If I take an Advil, it goes away. Sometimes it hurts really badly, and other times it just twinges. This happens several times a day, but is more prominent at night. It used to go away if I massaged my gums, but not anymore. If I'm standing upright, it doesn't bother me. I can actually feel which teeth hurt more than others when it comes on.I also cough really hard 3 or so times a day.. I can hear a wheeze in my throat which clears if I can loosen the phlegm. I am not a smoker. The cough, though really dry to start, doesn't bother me as much as the mouth pain...
