Sinuses are small air filled cavities in the skull bone and are located on the cheekbones, forehead and the nasal region. The main function of the sinuses is the secretion of mucus and voice resonance. The inner lining of the sinus, or the mucous membrane performs the function of secreting mucus as a lubricant. The body, on an average, produces half a gallon of mucus and saliva in the lungs, throat, nose and sinuses everyday. Sinus drainage is caused by everyday functions of swallowing and occasional blowing of the nose and it occurs everyday. This is an involuntary function, which often occurs without our notice. Sinus drainage is noticeable only when the drainage leads to sore throat due to some infection or it becomes so thick that there is a little difficulty while swallowing. To prevent abnormal drainage, sore throat and runny nose, it may be helpful if you undergo treatment for these symptoms to stop the infection from spreading. Why Does Sinus Drainage Occur? Daily drainage of the sinuses is quite normal and is hardly a matter of concern. Lubrication of the nose to prevent dust, pollution and infections from infecting the inner lining of the respiratory tract is the main function of this drainage. The reason why sinus drainage makes you cough is that you may have contracted a bacterial or viral infection. Throat infection is caused when harmful bacteria and virus enter the body through contaminated air, water and food. Sinusitis can also lead to drainage, sore throat and other infections. Individuals suffering from nasal congestion also show symptoms of sinus infection, sore throat and often a blocked nose which may result in cold and flu. Sinus Drainage and Sore Throat Treatment Nasal or sinus drainage, sore throat and runny nose, accompanied by watery eyes are the most common signs of common cold or sometimes flu. They also indicate the presence of allergies in the body. If the condition is not so severe, you can use medication for this respiratory problem that is easily available over the counter. For treating nasal drainage, a vaporizer or humidifier can be used to clear the passages and reduce the infections in the sinus passage. Another effective remedy is the use of warm water with a pinch of salt and baking soda. Spray this solution into the nostrils with the help of a nasal bulb syringe to reduce the congestion and clear the nasal passage. Neti pot is also another treatment method to clear the sinus infection. A solution made of warm water and salt is gently poured into one nostril by slightly tilting the head so that the sinus cavities fill with the saline solution. Once the sinuses are filled, the water slowly drains out of the other nostril. This method is very beneficial to clear the congestion of mucus caused due to nasal drainage. Sore throat, also known as strep throat can be treated by gargling with warm water and saline solution. If soreness persists even after trying these remedies, then consult a doctor who may prescribe antibiotics to fight infections. Apart from these remedies, keep your body well hydrated by drinking lots of fluids, soups and broths. Get ample rest to conserve energy which will help fight the symptoms related to cough and cold. Sore throat, often accompanied by sinus problems can be cured with the help of certain medications. If you feel the severity of sinus drainage, sore throat or any other symptoms, consult your physician, who may prescribe appropriate treatment for relief from this problem. Stay healthy!
