An introduction to aching joints and flu
Aching joints and muscles are two of the most common symptoms of the flu, and are part of the reason why you feel so much worse than when suffering from the common cold. Joints may feel stiff and sore, but you should be able to fully move them, even if it is achy to do so. Additionally, they should not be red or swollen, so if you experience these symptoms, then it is worth seeking medical attention to rule out any underlying causes of your joint pain.
Why does the flu make my joints ache?
When you are already suffering from fever, coughs and headaches, it seems unfair that aching joints should be added to the list of symptoms. One task of white blood cells is to repair and rebuild muscle fibres which are damaged from day to day. However, when you have the flu, your immune system diverts the white blood cells from this function to fight off the flu virus, thus leaving your muscles and joints feeling sore and achy.
In addition, white blood cells produce a chemical called cytokines when fighting the infection. This causes inflammation in muscles and joints, resulting in pain in a similar way to mild arthritis or rheumatism. However, this achy feeling is temporary, and once your body has fought off the infection, symptoms of achy joints will ease.
Are there home remedies to help me?
First of all, it is worth giving your muscles plenty of time to rest and relax. Trying to carry on as if you are perfectly fit and healthy will slow recovery as your body will not be able to put valuable energy into fighting off infection. As white blood cells are diverted from the muscles into fighting infection, your muscles are more susceptible to wear and tear. Thus, allowing your body to rest should prevent worsening of muscle pain.
You may also find relief from warming or massaging your joints. Some people find a warm cloth around painful joints is comforting, others find that a rub of warm olive oil or peppermint oil soothes your muscles or joints.
It can also be very soothing and refreshing to have a warm bath, particularly with bath salts or essential oils. If you are looking to reduce a fever, a bath like this may help to lower your temperature.
