Another cause of sinus infections is a result of bacterial invasion within one or more of the sinus cavities. Any bacteria that enter the nasal passages and sinus cavities through the air that is inhaled, are trapped by the mucus secreted by the mucous membranes surrounding these areas. These trapped particles can cause an irritation to these linings resulting in swelling and inflammation. “Bacteria that normally cause acute sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis (WebMD). These microorganisms, along with Staphylococcus aureus and some anaerobes (bacteria that live without oxygen), are involved in chronic sinusitis. (WebMD)” Fungi can also cause chronic sinusitis.
Chronic rhinosinusitis represents a multifactorial inflammatory disorder, rather than simply a persistent bacterial infection.  The medical management of chronic rhinosinusitis is now focused upon controlling the inflammation that predisposes patients to obstruction, reducing the incidence of infections. However, all forms of chronic rhinosinusitis are associated with impaired sinus drainage and secondary bacterial infections. Most individuals require initial antibiotics to clear any infection and intermittently afterwards to treat acute exacerbations of chronic rhinosinusitis.
I have had a problem with my sinuses ever since I had my teeth cleaned in Feb of this year.
I went to the doctor and she put me on antibiotics over 5 times and they never cleared up the infection because I still have pain in one side of my nostril on the right side and my right ear hurts and I have swelling on the right side of my throat that feels like an infection. I have had this problem ever since they worked on one of my front teeth that had a cavity in it. I can’t see the cavity anymore because they filled it in with a feeling but
I have had pain in it ever since they drilled in it and whenever I drink cold or warm stuff the sensitivity is horrible. I think it is a teeth problem probably a sinus tooth infection and Im going to a dentist to maybe get a root canal in it because I cannot stand the pain anymore and the pain infects my ear and my other teeth.
I have had this problem for over 4 months now and I cant stand it anymore.
