Sinusitis, commonly known as a sinus infection, involves inflammation of the tissues lining the sinus cavities behind the forehead, cheeks, and nose. This condition causes various symptoms. This article explores the connection between chills and sinus infections and outlines other common symptoms.
Understanding Chills and Sinus Infections
Chills can occur with a sinus infection, though they are not always a primary symptom. They are typically a bodily response to fever, which sometimes accompanies a more severe sinus infection. A fever indicates the body is actively fighting an infection by raising its core temperature to create an environment less favorable for invading viruses or bacteria.
When the body’s internal thermostat sets a higher temperature target to combat infection, you might feel cold because your current body temperature is below this new set point. This sensation triggers rapid muscle contraction and relaxation, leading to shivering, which is the body’s method of generating heat to reach the elevated temperature goal. While a low-grade fever can accompany both viral and bacterial sinus infections, significant chills often suggest a more pronounced inflammatory or infectious process, particularly with bacterial sinusitis.
Other Common Sinus Infection Symptoms
Beyond the potential for chills, several common symptoms indicate a sinus infection. Nasal congestion and stuffiness are frequently experienced. Thick, discolored nasal discharge, often yellow or green, is another characteristic sign, resulting from the body’s immune response to the infection.
Facial pain or pressure, particularly around the eyes, forehead, and cheeks, is a hallmark symptom, often worsening when bending over. This pressure can lead to headaches, and mucus draining down the back of the throat, known as post-nasal drip, can cause a persistent cough, especially at night, and a sore throat. Other symptoms include fatigue, bad breath, a reduced sense of smell, and sometimes tooth pain or ear pressure. Unlike a common cold, which usually resolves within 7 to 10 days, sinus infection symptoms often persist longer, sometimes for weeks.
When to Seek Medical Attention
It is important to know when to consult a healthcare professional for a sinus infection. Seek medical attention if symptoms persist for longer than 10 to 14 days without improvement, or if symptoms initially improve but then worsen. Severe facial pain or a debilitating headache warrants a medical evaluation.
High fever, especially if it exceeds 102°F (39°C) or lasts longer than three to four days, is another indicator to seek professional help. Prompt medical attention is needed if you experience vision changes, such as swelling or redness around the eyes, double vision, a stiff neck, or confusion. These signs can suggest a more serious infection or potential complications, and a doctor can accurately diagnose the condition and determine if antibiotics or other treatments are necessary.
