Re: sinus infection on one side of my face??
Yes, sinus infections can happen on one side.
Remember that you have 4 types of sinuses; Ethmoid (around the eyes), Sphenoid (at the temples), Frontal (the forehead), and Maxillary (beneath the eyes and in the cheeks). One of these cavities can be infected. When more than one becomes infected, it is called "pan sinusitis."
These infections are caused by several factors
1. An upper respatory tract infection causes a secondary infection in the sinus area -usually easily taken care of through antibiotics.
2. A deviated septum and structural abnormalities cause swelling in the soft tissue of the sinuses, blockage, and ultimately infection. This usually requires surgery to fix (I go in Friday). Antibiotics will simply prolong the inevitable.
3. Nasal Polyps create an obstruction, and therefore, infection. This is corrected through steroids or a simple surgery. Antibiotics may be needed to clear the infection.
All 3 of these things can happen, if you are unlucky.
The antibiotics that are commonly used to treat Sinus infections are Levaquin, Avelox, or in minor cases, Amoxicillan. 14 days is the recommended duration, depending on severity. Some people have to take them for longer.
Because you have had repeat sinus infections, you are either suffering from soft tissue inflammation, or perhaps a structural abnormaility (deviated septum, bone spur, etc.) Most likely both. Go to an ENT and get an endoscopy done (they stick a snake-like tube up your nose). The doctor may also ask for a CT scan, which will show him the presence of bacteria, and the extent of any structural problems.
I would not sit on this. It can get really out of control (like it did with me). You can develop chronic bacterial sinusitis. Be aggressive with your doctors, and if they say that you have a deviated septum, ask about surgery to correct it. To may people take this thing lightly. After 4 months of hell, I'll never take it lightly again.
