A fever is a natural response to infection by viruses or bacteria. It is your body’s way of fighting the infection and bringing your temperature back to normal as soon as possible. A high temperature also helps destroy harmful microorganisms that may have entered your body. A sinus infection with its characteristic symptoms such as congestion, pain, pressure, and mucus discharge can cause a fever. However, it is not a universal sign of infection but only in certain cases and under specific circumstances. Read on to know more about whether or not a sinus infection can cause fever.
Can Sinus Infection Cause Fever?
A sinus infection can cause fever in rare cases. The reason behind this is that bacteria and viruses are present in the sinuses, but it is not easy for them to get into the bloodstream. However, if they do get into the bloodstream and infect your body, you may develop symptoms of an infection like fever.
What Is A Fever?
A fever is a condition where your body has an increased temperature, generally above normal levels. It is caused by an increase in your body’s production of the hormone called “Interleukin”, which is responsible for triggering a rise in body temperature at the site of infection. Fever is a common symptom of all infections, including infections in the sinuses. However, not all people with a fever have an infection. Fever is also not always a sign of a bad infection. Depending on the cause of the fever, it may be helpful or harmful.
How Does A Sinus Infection Cause Fever?
- The most common cause of fever in people with a sinus infection is a bacterial or viral infection.
- Bacterial infection occurs when bacteria infect the sinuses and spread to the rest of your body causing an infection.
- Viral infections occur when viruses infect your body and spread to the rest of your body causing an infection.
- An allergic reaction can also cause fever in people with a sinus infection, but this is very rare.
- The immune system can also trigger fever due to an allergic reaction or a severe cold or flu, but this is also uncommon is very rare.
- Fever can also occur due to the immune system overreacting when it reacts to a substance in the body that does not cause an infection.
- An infection in the sinuses can also cause fever if it spreads to the rest of your body causing an infection.
- A sinus infection can also cause fever if it causes inflammation at a site other than the sinuses, like your throat or lungs, and spreads to your bloodstream causing an infection.
- Fever is also caused by bacterial or viral infections that spread from another part of your body causing an infection such as a skin rash, vagina or penis infections, eye infections, ear infections, etc. However, this is rare and not common in people with a sinus infection because these types of infections usually cause other symptoms apart from fever such as pain, swelling, and redness rather than fever alone like congestion and headache which are more common symptoms of sinus very rare.
- A fever can occur when you have an infection in your bloodstream, such as from a virus or bacteria. In this case, there is an increased risk that your body will not fight the infection effectively and you may develop severe symptoms of an infection like fever, cough, and chills.
- A sinus infection does not cause fever in all people with a sinus infection at all times. Only certain people with sinus infections will develop a fever after having an infected sinus. Therefore, it is important to note that there are some cases where it is normal for people with a sinus infection to have a high temperature without having any signs of an infection or without any other symptoms at all. You are rare.
- A non-infectious fever is a common condition that causes fever in people who have a sinus infection and are not actually infected. The cause of the fever is unknown but it may be caused by airway obstruction, such as a cold, allergies, or asthma.
When Does A Sinus Infection Cause Fever?
- If a sinus infection lasts longer than 7 days
- If the person has other symptoms such as cough, nasal congestion, or headache
- If the person has an underlying health condition (such as asthma) that makes it more likely for him/her to get a sinus infection
- If the person is on antibiotics
- If the person has a weakened immune system due to another medical condition like HIV/AIDS, cancer, or organ transplantation
- If the person is a child
- If the person is a woman who has had a baby, or if she has given birth to a baby in the past year
- If the person is an elderly person or someone who takes drugs that affect his/her immune system or blood clotting ability (like warfarin)
- If the person has recently been exposed to a disease that can cause fever (such as chicken pox or measles)
- If the person is an infant, elderly, or very young child who has not yet developed a full immune system
- If the person is a very young child who has been exposed to chickenpox or measles
- If the person has recently had a sinus infection that was complicated by underlying health problems (such as asthma)
A sinus infection can cause fever in some cases. A person with a sinus infection will generally have symptoms such as a runny nose, facial pain, headache, and a feeling of unwell. If any of these symptoms are accompanied by a fever, then it could be because of a sinus infection. A fever is a sign of an immune response by the body when it detects the presence of an infection. It is helpful as it kills harmful bacteria and brings the temperature back to normal. In the case of a sinus infection, a fever may be present only when there is a bacterial infection.
