A runny or stuffy nose, incessant sneezing, post-nasal drip, watery eyes, and a sore throat - these are some of the classic symptoms of the common cold, which we easily recognize. But not many of us aware of the fact that an episode of common cold can often turn into something more serious - like sinusitis. It has been observed that acute sinusitis, which is the most common type of sinusitis, is often followed by a recent episode of cold. Sinusitis refers to the inflammation or swelling of the air-filled cavities located in our forehead and behind the cheekbones. An inflammation of these cavities can cause a buildup of mucus within them, which can increase the risk of infections. It has been observed that nasal congestion caused by common cold can raise the risk of getting a sinus infection considerably. To prevent this, it is very important to recognize the progression of cold to sinusitis. However, it is not as easy as it sounds, as both the conditions share several symptoms. So, let's find out how to recognize and prevent the advancement of cold into a sinus infection or sinusitis. Apart from common cold, sinus infections can be caused by several other factors like viral or bacterial infections, nasal polyps, allergies, fungal infections, and a deviated septum. However, common cold can cause nasal congestion, which can block the sinus passages and increase the risk of an infection. This is the reason why sinusitis or sinus infections are so common during the cold and flu season. However, the symptoms of both these conditions are more or less similar, due to which telling the difference between a cold and a sinus infection can become quite difficult at times. But if symptoms - like thick nasal mucus, a persistent headache, post-nasal drip, pressure and tenderness around the eyes, a cough that is worse in the morning, toothache or sensitivity, and reduced sense of taste and smell - last for more than a week, then it can be a sign that your cold is turning into a sinus infection. If you realize that your cold symptoms have lasted longer than they should, then follow these preventive measures to avoid a possible sinus infection. If you want to avoid a sinus infection and get rid of those unpleasant cold symptoms as soon as possible, then drink about 10 to 12 glasses of water daily. Along with water, you can drink chicken or vegetable soup and broth to keep yourself well-hydrated. This will help thin the mucus and facilitate its drainage. Coffee and tea are known to dehydrate the body. Therefore, it is better to avoid them for a few days until your cold symptoms subside. By irrigating your nose with saline water, you can keep your sinuses clear by promoting their drainage. You can use commercial saline nasal sprays or make a saline solution at home by adding a small amount of salt to a cup of warm water. You can use a neti pot to irrigate your nose with this saline solution. Nasal congestion can block the sinus passages and prevent their drainage. This can create a favorable environment for the growth of infectious agents. Decongestants can help you get relief from nasal congestion and thus reduce the risk of developing a sinus infection. However, don't use decongestants for a long time, as prolonged use can cause 'rebound' congestion. While smoking has many dangerous effects, it is particularly bad if you are suffering from a cold or cough. Tobacco and the smog produced from burning a cigarette can worsen the cold symptoms and irritate the lining of the sinuses. This can increase the risk of getting a sinus infection. Like cigarette smoke, exposure to environmental pollutants like chemicals, fumes, and dust can also irritate the delicate lining of your nasal passages and sinuses. Wash your hands frequently with soap and water to prevent the germs from spreading. Sinusitis is often caused by viral and bacterial infections. So make sure that you wash your hands before and after blowing your nose. To keep your cold from becoming a sinus infection, it is very important to blow your nose gently. Forceful blowing can push back thick mucus into your sinuses and thus spread bacteria and other harmful microorganisms that can cause an infection. Steam inhalation is one of the most effective home remedies for relieving nasal congestion. Just fill a pot with hot water and hold your head over the pot to breathe in the steam. If the water is too hot, then let it cool down a bit. You can also take a hot shower to ease your nasal congestion. A warm compress can also help relieve congestion and ensure better drainage of mucus. You can place a hot and damp towel on your face for 5 to 10 minutes several times a day to clear up your nasal passages. These simple home remedies will not only help prevent a cold from turning into a sinus infection, but also speed up the recovery process if you have already developed an infection of the sinuses. But, if these remedies fail to prevent a sinus infection, and your sinusitis symptoms are not improving at all, then talk to your physician.
