Most people expect a cold to bring a familiar set of symptoms. A blocked nose, sore throat, coughing and fatigue are all part of the experience. What many do not expect is to wake up one morning and feel as though the room is spinning around them.
Yet this is exactly what happens to some people during or shortly after a viral infection. Vertigo is not a typical cold symptom, but doctors have long recognised that certain viruses can affect your balance. This can cause a dizzy feeling of spinning, swaying or movement that makes even simple tasks feel hard.
If you have ever felt unusually dizzy while recovering from a cold, you may have wondered if the two are connected. In some cases, they are.
What Is the Difference Between Dizziness and Vertigo?
Vertigo is often confused with general dizziness, but they are not the same. Dizziness can mean many things, from feeling lightheaded to feeling weak or unsteady. Vertigo is the specific feeling that you or your surroundings are moving when they are actually still.
Some people describe it as feeling like they have just stepped off a spinning fairground ride. Others say it feels as though the floor is shifting. Depending on the cause, vertigo may also come with nausea, vomiting, balance problems or trouble focusing your eyes.
The sensation can be scary, especially when it starts during what seems like a normal cold.
How Viral Infections Affect Balance and Cause Vertigo
The link between a runny nose and a spinning room might not seem obvious. However, your ears play a much bigger role in balance than most people realise.
Deep inside the inner ear is a complex system of fluid-filled parts. These parts constantly send signals to the brain about your movement and position. Along with your eyes and muscles, they help keep you balanced.
When a viral infection causes swelling in these delicate systems, your balance signals can get mixed up.
One possible cause is vestibular neuritis. This is when the nerve that carries balance information to the brain becomes inflamed. Scientists think viral infections are a common trigger. This condition can cause sudden vertigo that lasts for hours, days or even longer.
Another cause is labyrinthitis, which is swelling of the inner ear itself. Unlike vestibular neuritis, labyrinthitis can affect both balance and hearing. Some people feel vertigo along with ringing in the ears, muffled sound or temporary hearing loss.
These conditions are quite rare compared to the millions of normal colds people get each year, but they are known results of certain viral infections.
Can Ear Pressure During a Cold Cause Vertigo?
Not every case of dizziness during a cold is caused by swelling in the inner ear.
Colds often cause congestion in the tubes that connect your middle ear to your throat. These are called Eustachian tubes, and they help manage the air pressure in your ear.
When these tubes get blocked, pressure can build up behind the eardrum. Many people feel a sense of fullness or muffled hearing. Sometimes, these pressure changes can affect your balance and make you feel dizzy.
Fluid buildup from a cold can also cause balance issues. While these symptoms usually go away quickly, they can be annoying and worrying.
Common Causes of Dizziness During a Viral Infection
It is important to remember that not all dizziness during a cold comes from the ear.
A fever can make you feel weak and lightheaded. Being dehydrated can also make you feel dizzy, especially when you stand up fast. Fatigue, poor sleep and some cold medicines can also be the cause.
This is why doctors look at all your symptoms before deciding if your dizziness is vertigo or something else.
When to See a Doctor for Vertigo and Dizziness
Most balance problems get better as your cold goes away. However, some symptoms should always be checked by a doctor.
See a doctor if your vertigo is severe, lasts a long time or comes with hearing changes. Sudden hearing loss needs to be checked quickly to get the best treatment.
You should also get help right away if you feel dizzy and have trouble speaking, facial weakness, double vision, a bad headache, numbness or trouble walking. These could be signs of a more serious problem.
Even if your symptoms are not severe, talk to a doctor if the vertigo continues after your cold is gone or if it makes your daily life difficult.
How to Treat Vertigo Caused by a Cold
For many people, recovery starts once the virus goes away and the swelling stops. Drinking plenty of water, resting and moving carefully can help you feel better.
If the vertigo is caused by vestibular neuritis or labyrinthitis, doctors might give you medicine for nausea and dizziness. Some people also do physical therapy to help their brain adjust to balance changes.
Recovery times vary. Mild symptoms might improve in a few days, while some people have balance issues for a few weeks. Most people get back to normal as their body recovers.
Summary: Understanding Cold-Related Vertigo
A common cold is usually just a small problem. But sometimes, the viruses and swelling can affect your balance and cause vertigo.
The experience can be scary, but it is often temporary and gets better as you heal. Knowing the link between infections and the inner ear helps explain why a simple cold can sometimes feel like more than just the sniffles.
If the spinning feeling is severe, persistent or comes with hearing loss, seeing a doctor is the best way to stay safe.
