Sinus Infection
Sinus infection, or sinusitis, is an inflammation of the sinuses and nasal passages. A sinus infection can cause a headache or pressure in the eyes, nose, cheek area, or on one side of the head. A person with a sinus infection may also have a cough, sore throat, fever, bad breath, and nasal congestion with thick nasal secretions. Sinusitis is categorized as acute (sudden onset) or chronic (long term, the most common type).
Infection in nasal passages and pharynx spread into the sinus easily because it is all connected. The sinus and the nasal cavities are there to warm and filter the air you breathe.
Bacteria, fungus and other allergens, particles and organisms can easily travel up into your sinus cavities from your nose. Believe it or not studies have shown that just blowing your nose will cause them to enter the sinus cavities. Normally these would be eliminated in the sinus drainage that typically goes down into throat. But if the organisms or matter cause swelling of the lining of the sinus cavities then the area gets blocked because of narrowed sinus passages and the sinus drainage hardens and backs up not allowing the quart of mucous to move through that needs to every day. Then an infection can start in the sinus cavities called sinusitis (sinus infection- same thing), because of this back up. So an infection would not likely start in the nasal passages – I’m assuming you mean nose. Irrigation with saline solution (salt water) is your best treatment.No other chemicals, herbs,irritants etc. should ever be put up into your sinuses according to my GP.
It’s the first time in my life I encounter such problem so I had to make a research to understand everything. Now it’s clear to me and now I’m feeling a lot better and still using saline solution.
