Re: sinusitis 10 years now
It's not very likely that you've had a sinus infection for 10 years as that would lead to extremely serious medical complications (and any doctor would be able to recognize and treat the infection with antibiotics even if they weren't successful in addressing the underlying cause).
The normal course of treatment for chronic sinus inflammation tied to mold exposure or allergies involves several things:
1. Antibiotics to treat any acute infection (often 30 days or more of antibiotics are necessary if there is an infection that hasn't responded to a shorter course of antibiotics).
2. Daily saline irrigation with a SinusRinse bottle, neti pot or pulsatile irrigation system (WaterPik, etc.) to help rinse away mucus (sometimes using anti-fungal medication if the inflammation is mold-related).
3. Use of prescription anti-inflammatory nasal sprays (Rhinocort, Flonase, etc.) to keep the sinus open and draining.
4. Allergy testing followed by the appropriate treatment (shots or daily antihistamines).
One other potential cause that is sometimes overlooked is GERD (acid reflux) which can cause or exacerbate sinus inflammation and cause chronic sore throats and post-nasal drip.
The post-nasal drip by itself won't cause cancer but that doesn't make it any less annoying so hopefully your docs can figure out what the underlying cause of the problem is so you can put this behind you.
