Why your whole body aches when you’re sick (and what you can do about it)

Coming down with a cold, virus or the flu is never fun. But sometimes you can push through if the symptoms aren’t too bad. Have a sore throat? Gargle. Feeling congested? Take a steam shower. Mild fever? Take fever-reducing medicine. It’s bearable, though not ideal.

But once full-body aches set in (often accompanied by a fever), you may quickly find yourself out of commission. Unlike the muscle aches that can come on after one too many squats, body aches from an illness tend to cause dull pain and discomfort everywhere.

The good news is you can find some relief from full-body aches right in the comfort of your home. Here’s what you need to know:

What causes body aches when you’re sick?

When you have the flu, a common cold, a virus or a bacterial infection, your immune system jumps into action. It reacts by releasing white blood cells to fight off the infection. The reaction causes inflammation, which can leave your muscles feeling achy.

The good news is that your achiness is a sign that your body is fighting off the illness. But the harder your body works, the more severely the body might ache.

Full-body aches are also often accompanied by other symptoms including:

• Fever
• Weakness
• Fatigue
• Shivering or body temperature changes
• Cold and flu-like symptoms

What helps body aches

The best way to diminish full-body aches is to treat the underlying cause of the aching. But as you’re waiting for treatment to kick in — or just waiting for a virus to run its course — try to:

Stay hydrated

Some symptoms of cold and flu — such as sweating, vomiting and diarrhea — can leave you dehydrated. But water is essential to your body’s normal functioning and its ability to fight infection. Drink plenty of water, broth, tea or electrolyte drinks. Soup is also a great way to stay hydrated, especially if you are struggling to eat solid foods.

Use heat to relax your muscles

Heat can loosen muscles and provide relief from body aches. If you don’t have a severe fever, a warm bath or shower can be relaxing. But avoid making the temperature too hot — keep the water just above lukewarm to maintain your body temperature. Heating pads or blankets can also offer some comfort, but avoid excessive heat and don’t use them if there is a chance you may fall asleep.

Regulate your body temperature

Full-body aches often go hand-in-hand with a fever. As a higher body temperature causes you to shiver, your muscles tense up and may begin to ache. To regulate your body temperature, reach for fever-reducing pain medicine, take a cool bath and use only a thin blanket or sheet.

Rest

Research shows that the immune system and sleep are closely connected. Sleep strengthens the body’s defense system. And when the body is fighting infection, it craves more sleep. The problem is that when you are sick, other symptoms often make it hard to sleep soundly. Try to rest as much as possible — it will relax your muscles and speed up the healing process.

Take over-the-counter pain medication

Common pain relievers may help you feel better but be sure to choose non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen. NSAIDs have anti-inflammatory properties and block the body’s production of inflammation-causing chemicals. As a bonus, NSAIDs also help reduce fever to regulate body temperature.

When to see your doctor about full-body aches

Body aches from a viral illness typically clear up in a couple of days and improve with home remedies. But if your body aches haven’t gotten better after 3-5 days, check in with your primary care physician (PCP).

See a doctor sooner if your body aches:

• Appear after a tick bite
• Accompany severe redness or swelling
• Occur with a rash

If you don’t have a fever or other symptoms, and you experience body aches often or for prolonged periods of time, make an appointment with your PCP. It could be a sign of a drug reaction or a more severe and chronic underlying medical condition, such as an autoimmune disease.

If you have body aches that aren’t improving, reach out to your primary care physician.

Low Grade Fever and Body Aches

April 8, 2016

A low grade fever and body aches are common signs of influenza, or the flu. Headache and fatigue often accompany a fever and body aches, especially if one is suffering from the flu.

The best way to avoid fever, body aches and other flu symptoms is to get the flu shot. This is especially true for children, the elderly, and anyone with a compromised immune system.

The Flu Can Cause Body Aches and Fever

A fever is typically a sign that the body is fighting infection. A fever is typically considered “low grade” if it is between 99.9 and 101 degrees Fahrenheit. However, fever in children and particularly infants should be watched carefully. A newborn with a temperature of 101 degrees Fahrenheit needs emergency medical attention.

When you have a viral infection like the flu, your body diverts white blood cells to fight the infection. Those white blood cells are normally assigned to keep your joints and muscles in optimal working order. When they get called away, you develop body aches.

Unfortunately, if you have the flu, you are probably contagious. Most adults become contagious a day before symptoms start and remain contagious for up to seven days. Children sometimes are contagious for longer periods.

Treatment for Flu-Like Symptoms

Common at-home treatments for a low grade fever and body aches include:

• Rest.
• Drink plenty of fluids.
• Take over-the-counter medicines such as acetaminophen or aspirin.

Breaks the body at a temperature, what to do?

The cause of pain in muscles, joints and bones during fever often lies in intoxication, that is, poisoning of the body ¹ . As “poisons” are bacterial toxins, products of inflammation and decay of tissues in the affected areas, substances that appear in the body due to metabolic disorders against the background of the disease ¹ . At the same time, the severity of symptoms of intoxication primarily depends on the type of infectious agent and the body’s ability to resist it ¹ .

Infectious diseases are more commonly caused by:

• viruses, such as influenza, parainfluenza, adenoviruses, hepatitis viruses, infectious mononucleosis, measles, varicella, and others;
• bacteria: staphylococcus, streptococcus, salmonella, tubercle bacillus, etc.;
• protozoa: amoeba and giardia;
• mushrooms ² .

The vast majority of all infections are acute respiratory viral diseases ^2.3 . Their pathogens can be:

• influenza viruses – about 15% of cases;
• parainfluenza – up to 50%;
• adenoviruses – up to 5%,
• respiratory syncytial virus – about 4%;
• enteroviruses – 1%;
• viral associations – about 23%;
• other viruses ⁴ .

All of these viruses can infect the mucous membrane of the upper respiratory tract. They penetrate the epithelial cells of the nasal cavity and pharynx, causing local inflammation and death of these cells ^3.4 . Absorption into the bloodstream of inflammation and decay products leads to the development of an intoxication syndrome, accompanied by body aches and fever, weakness, headache and other symptoms ^3.4 .

Intoxication is most pronounced in influenza ^4.5 . Its appearance precedes the symptoms of respiratory tract damage.

• Body temperature rises to 39-40 °C ⁴ chills occur.
• Starts to have a headache in the forehead and temples.
• Sudden sounds and movements aggravate headache.
• There is pain and pain in the eyes, aggravated by the movement of the eyeballs and pressure on them.
• Eyes become red and watery.
• Aches and pains in muscles and joints.
• Acute weakness and lethargy seizes the whole body ⁵ .

According to statistics, muscle pains accompany influenza in 40% of cases. Muscle weakness occurs in 87% of patients ⁴ .

Additional manifestations of intoxication may be vomiting, sometimes occurring in children, dizziness and fainting, which are more common in adolescents and elderly patients. Possible sleep disturbance in the form of insomnia ⁵ .

The manifestations of SARS caused by other respiratory viruses (not the influenza virus) are similar to each other ⁴ . According to the severity of the intoxication syndrome, these diseases are an order of magnitude inferior to influenza ⁴ .

So, rhinovirus infection , although it begins acutely, with sneezing and the appearance of copious watery discharge from the nose, is almost never accompanied by body aches and fever – the temperature rarely rises to 38 ° C, and sometimes even remains normal ⁴ .

With parainfluenza from the first day, sore throat, dry hacking cough, hoarseness are disturbed, and manifestations of intoxication are limited to a rise in temperature to 37.5 ° C, mild weakness and headache ⁴ .

Adenovirus infection is characterized by high and prolonged fever, runny nose, conjunctivitis, sore throat associated with damage to the pharyngeal tonsils, swollen lymph nodes. However, despite the impressive set of symptoms and high temperature, the muscles and joints do not hurt – some weakness and heaviness in the head are possible ⁴ .

Respiratory syncytial infection also occurs with moderate intoxication: weakness, lethargy, headache, discomfort in the muscles of the body – but the resulting discomfort is not comparable to what happens with the flu. Along with the intoxication syndrome, there is a cough with shortness of breath, wheezing and viscous sputum ⁴ .

Fever and chills – features of the course

High fever accompanied by chills is often a symptom of influenza or SARS

High body temperature accompanied by chills is a symptom of influenza or SARS ^1.2 and helps to identify this disease.

Features of the course

Bacterial and viral infections, such as influenza or SARS, may be accompanied by symptoms such as fever and chills. ^1.2

An increase in body temperature is part of the body’s defense response to an active infection. ³ The anterior hypothalamus in the brain increases body temperature ⁴ up to 38°C or more, which gives the effect that we perceive as a fever. ⁵

Fever should not be confused with hyperthermia, which occurs when the body generates more heat than it can dissipate. ³ Hyperthermia is most often the result of wearing excess clothing that is inappropriate in hot weather or high humidity, or after strenuous physical activity. ⁴

Chill manifests itself in the form of rapid muscle contraction and relaxation, visually perceived as a shiver. Chills are often observed before the onset of fever. ²
