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 or the cheek area. It may go uptill the neck. Sinusitis is an inflammation of the paranasal sinuses, which may or may not be as a result of infection, from bacterial, fungal, viral, allergic or autoimmune issues. 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, a 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). Some of the home remedies for sinus infection are as follows:

Breathe warm, moist air from a steamy shower, a hot bath, or a sink filled with hot water. Avoid extremely cool, dry air. Consider using a humidifier to increase the moisture in the air in your home.
Use saltwater nasal washes (saline lavage or irrigation) to help keep the nasal passages open and wash out mucus and bacteria. You can purchase saline nose drops at a pharmacy or make your own saline solution at home. It may also help to gargle with warm salt water by using one teaspoon of salt per pint of water.
Avoid cigarette smoke and polluted air. Tobacco smoke and air contaminants can irritate and inflame your lungs and nasal passages.
Use a humidifier. If the air in your home is dry, such as it is if you have forced hot air heat, adding moisture to the air may help prevent sinusitis. Be sure the humidifier is clean and free of mold.
Apply warm compresses. Place warm, damp towels around your nose, cheeks and eyes to ease facial pain.
Drink plenty of fluids. Dilute mucous secretions and promote drainage by consuming additional fluids.
Hot soups do indeed help congestion. The hot steam from the soup may be its chief advantage. In fact, any hot beverage may have similar soothing effects from steam. Ginger tea, fruit juice, and hot tea with honey and lemon may all be helpful.
Humidify your home. Running a cold-mist machine in your bedroom will keep your nasal and sinus passages from drying out.
Drinking extra liquids—both hot and cold—throughout the day thins out the mucus and keeps it flowing.
Make a weak salt solution with warm water. Put solution into a small tea pot with a spout. Tilt your head to the left side, put the spout into the exposed right nostril and let the water run into that nostril. Now wait for some time. The solution dribbles through your sinusis and then exits through the left nostril where gravity helps it leak out. Tilt head to the other side and repeat. Do this every morning to clean out your sinusis.
A decoction of mustard seed powder and water, instilled in the nostrils; eating jalapeno peppers; drinking juice of ripe grapes; applying a paste of cinnamon and water on the forehead.
By inserting a cotton swab in the nasal passage after dipping the cotton swab in the hydrogen peroxide. Do this in each nasal 4 or 5 times about 30 minutes after the nasal irrigation.
