Yes, it is very common to get back pain when you are sick. Illnesses like the flu, a cold, or a respiratory infection often bring on muscle aches and back soreness. This pain is usually a normal part of your immune system fighting off the infection, and it typically fades as you recover.
Why Does My Back Hurt When I Am Sick?
The main reason is your immune system’s response to the infection. When your body detects a virus or bacteria, it releases chemicals called cytokines. These chemicals help direct immune cells to fight the illness, but they also cause inflammation.
This inflammation is a primary trigger for the muscle aches and generalized pain you feel all over, including your back. It is the same process that causes the fever and fatigue you experience. The pain is not usually a problem with your spine itself, but rather inflammation and tension in the muscles surrounding it.
Dehydration is another factor. When you are sick, you often lose fluids through sweating, fever, or reduced appetite. Dehydration can lead to muscle cramps and spasms, which can make back pain worse.
What Kind of Illnesses Cause Back Pain?
Viral infections are the most frequent culprits. The flu is famous for causing severe body aches and back pain. Colds, COVID-19, and other respiratory viruses can also cause this symptom.
Infections that affect the kidneys can cause back pain too. A kidney infection or kidney stones typically cause pain in the flank area, which is the side of your back just below your ribs. This pain is often sharper and more localized than the general muscle ache from a virus.
Less commonly, severe infections like meningitis can cause neck and back stiffness. This is a medical emergency. If your back pain is accompanied by a severe headache, high fever, and stiffness that makes it hard to touch your chin to your chest, seek emergency care immediately.
When Back Pain Means Something More Serious
Most back pain during an illness is harmless and temporary. But there are warning signs that point to a more serious problem.
Call a doctor right away if you have back pain along with any of these symptoms:
- Numbness or weakness in your legs
- Loss of bladder or bowel control
- A fever that is very high or does not go away
- Severe pain that does not improve with rest
- Pain that gets worse when you lie down
- Redness or warmth over the painful area
These symptoms could indicate a spinal infection, an abscess, or nerve compression. These conditions are rare but require prompt medical attention. Do not wait to see if they improve on their own.
How to Ease Back Pain While You Recover
Treatment focuses on managing symptoms while your immune system does its work. Rest is important, but complete bed rest is not recommended. Gentle movement helps maintain muscle function and prevents stiffness.
Over-the-counter pain relievers can help. Acetaminophen and NSAIDs like ibuprofen or naproxen reduce pain and inflammation. Always follow the dosing instructions on the label and check with a pharmacist if you have other health conditions or take other medications.
Applying heat can relax tense muscles. A warm heating pad or a hot shower can provide significant relief. Some people prefer cold packs for the first day or two to reduce inflammation. Use whichever feels better to you.
Stay hydrated. Drink plenty of water, broth, or electrolyte drinks. Hydration supports your immune system and helps prevent the muscle cramps that come with dehydration.
Sleep is when your body repairs itself. Try to get extra rest and keep your sleeping position comfortable. A pillow between your knees when sleeping on your side can help support your back.
Could It Be the Flu or COVID-19?
Back pain is a recognized symptom of both influenza and COVID-19. For many people, it is one of the first signs that they are getting sick.
The pain is typically described as a deep ache in the lower back or between the shoulder blades. It can be severe enough to make daily activities difficult. This type of pain usually appears alongside other symptoms like fever, cough, sore throat, or fatigue.
If you have back pain with any of these symptoms, it is reasonable to take a test for COVID-19 or the flu. Knowing what you have can help you decide on the right treatment and when to isolate from others. The back pain itself will usually resolve within a few days as the infection clears.
u Get Back Pain When Ur Sick: What Is Normal?
Normal illness-related back pain is a dull, aching sensation in the muscles. It may be constant or come and go. It often feels worse when you move, but it is not usually sharp or stabbing.
This type of pain typically lasts as long as the acute phase of your illness, usually three to seven days. As your fever breaks and other symptoms improve, the back pain should gradually fade.
If the pain persists for weeks after your other symptoms have resolved, it may no longer be related to the illness. It could be a separate musculoskeletal issue that was triggered or worsened by the infection. In that case, the usual treatments for mechanical back pain, such as physical therapy and gentle stretching, become more relevant.
You should never ignore back pain that is severe, getting worse, or accompanied by neurological symptoms. Trust your instincts. If something feels wrong, get medical advice.
What Not to Do for Sick-Related Back Pain
Avoid vigorous exercise while you are actively sick. Your body needs energy to fight the infection, not for a workout. Light stretching is fine, but intense activity can prolong your illness.
Do not take multiple pain relievers at the same time without checking for interactions. Many cold and flu products already contain acetaminophen. Taking an extra dose on top of that can damage your liver.
Do not use a heating pad while sleeping. You can fall asleep and leave it on too long, which can cause burns. Use it for 15 to 20 minutes at a time while you are awake.
Do not ignore new or unusual symptoms. Back pain with a severe headache and stiff neck requires immediate emergency evaluation. This combination can be a sign of meningitis.
Frequently Asked Questions
How long does back pain last when you are sick?
It usually lasts as long as the acute phase of the illness, typically three to seven days. If it persists for weeks after other symptoms resolve, it may be a separate issue.
What is the best way to sleep with back pain from being sick?
Sleep on your side with a pillow between your knees to keep your spine aligned. Use extra pillows to elevate your head if you have a cough or congestion.
Can a cold cause lower back pain?
Yes, a cold can cause generalized muscle aches, including in the lower back. This is due to the immune system’s inflammatory response to the virus.
When should I worry about back pain with a fever?
Worry if the fever is very high, lasts more than a few days, or the back pain is severe and localized. Seek emergency care if you also have a stiff neck, severe headache, or weakness in your legs.
