According to the National Library of Medicine, a sinus infection is the result of inflamed and irritated sinuses. Sinus infections are commonly caused by allergies, the common cold or environmental factors such as pollution. Identifying the early symptoms of a sinus infection will enable to you treat the infection early on, preventing further complications. Many of the early symptoms of sinus infection may be difficult to determine if they are the result of sinusitis, so seek medical advice before self-medicating.
Runny Nose
One of the earliest symptoms of a possible sinus infection is a runny nose. The nose will begin to secrete thin, clear mucus that will thicken and turn greenish-yellow over time. A runny nose may be the result of an allergic reaction, which can easily be treated with an over-the-counter (OTC) antihistamine such as loratadine. As the nasal drainage increases, you may experience postnasal drip, a condition where mucus drips in the back of the throat.
Nasal Congestion
Nasal congestion is another early symptom of a developing sinus infection. Most nasal congestion is the result of the sinus cavity becoming inflamed, cutting off the normal airflow and nasal drainage. This creates a moist environment which encourages the growth of bacteria, which can lead to infection. Take an OTC decongestant such as pseudoephedrine to keep the sinuses open, allowing drainage, which may prevent or shorten the duration of the infection.
Sinus Pressure
A common early sign of a sinus infection is sinus pressure, according to Familydoctor.org. Sinus pressure is the result of nasal congestion, which may cause discomfort or pain in the eyes, ears or upper teeth. As the nasal passages swell, they place pressure on various aspects of the head, leading to headaches. Sinus pressure headaches are commonly felt upon waking in the morning and will worsen with sudden movement or bending over. They generally improve throughout the day. Sinus pressure pain may be treated with an OTC anti-inflammatory pain reliever, such as aspirin.
Low-Grade Fever
If you have one or more of the above symptoms coupled with a low-grade fever, it is likely you are developing a sinus infection. The body raises its temperature to fight off infection naturally. You may experience chills with a low-grade fever. If your temperature rises above 100.5 degrees, the Mayo Clinic recommends seeking medical attention to determine the specific cause of the fever.
