Doctors... please help. So sick of being sick...?

Just trying to resolve an unresolved health issue here. I have been to the DDS 3 times, been to the Doc 2 times. Thus far, DDS said if it's a tooth problem, she will need to redo the recent RC we did in Dec. Doc said it could be a virus my body is trying to fight off (went to doc on Tues with temp 99.1). When doc looks in my nose, she said I have some allergies. Here's what I want to know... can a sinus infection cause pain in my left jaw that radiates down to the bottom area and effects other teeth as well? Is that possible? And if it is, is there a specific antibiotic for that? Considering i've had 3 rounds of Amox so far that work when I use it and then these symptoms return after a month... maybe it's sinus infection only on the left side? I do feel some pressure up there. Any advice?

THIS MIGHT BE SINUSITIS CAUSED BY ALLERGIES. THE AMOXICILLIN HELPS TO DECREASE THE INFLAMMATION WHICH CAUSES THE PAIN


A SINUS INFECTION MOSTLY CAUSES PAIN AND PRESSURE IN THE UPPER HEAD SINUSES AND IS EASY TO DIAGNOSE BY PINCHING YOUR NOSE AND BENDING FORWARD WHILE SITTING IN A CHAIR.


A ROOT CANAL MAY BE COINCIDENTAL.
Reply:hmmm.





go to an ear nose and throat specialist.
Reply:Well if it is a viral infection Amoxicillin, which is an antibiotic, will not help.





And yes, a sinus infection can cause inflammation and pain in the general area around your teeth and jaws. It could just be that it is a combination of allergies and any latent infection the root canal didn't clean it out. If you have a fever, though, the infection is bigger and your body's immune system is on the alert.





Another RC could help. Ask your doctor for some allergy medication, and if it's a viral infection you can try to wait it out.
