Re: Sinus cavity pain or tooth ache?
It does sound like sinus pain to me, but you should really go to a doctor and get it confirmed and refered to an ENT specialist. Best way to confirm sinusitis is by CT scan, though I'm not certain they always pick up some infections. I had CT scan in August, which was supposedly clear but my pain continued, so I had a second scan October 31st which showed sinus infection.
If it is a sinus infection, you really need a minimum 2 week course of antibiotics, though I think my infection is resistant, so I'm going back to doctor to see about a stronger dose/alternative antibiotic.
Also, regular flooding with saline/bicarbonate solution is recommended. I'm not sure the neti pot method would work for deep sinus cavities, as I'm not convinced the solution can reach that far doing it over sink.
look at the sticky on peroxide flushing...I've been doing that every day for last 10-11 days to kill bacteria in the sinuses to prevent re-infection when I finally kill this infection I have.
My ENT is against using decongestants (sprays and tablets) so I'm just on flixonase steroid drops and diclofenac which is an anti-inflammatory to reduce swelling of the sinus membranes.
Sinus pain does not usually respond to most painkillers such as paracetamol, codeine, tramadol etc.
