Back pain is emerging as a notable symptom among those catching the so-called 'American Covid' XFG Stratus strain, as confirmed cases continue to rise across the UK. According to UKHSA data, Covid cases increased by 13.5% week on week to October 7, with deaths up 46.4% and hospital admissions up 33.5%, a significant portion of which are attributed to the American Covid strain.
Rising cases and hospital data
For September, the UKHSA reported that the rate of positive Covid tests in hospitals increased from 5.9% to 7%, with more than half identified as the American Covid or Stratus variant of XFG. This strain was first identified last January and has since spread globally.
While back pain is not limited to the American Covid strain, many who have contracted Covid this year have reported the issue. According to American health firm ADA, Covid can cause back pain due to myalgia, a common complication of viral infections.
Why Covid causes back pain
ADA explains: "Back pain is a symptom that is often reported by those who have fallen ill due to the coronavirus. The primary source of this back pain stems from myalgia, which is characterised by muscle aches and pain. Myalgia is a common symptom of viral infections such as COVID-19 and may affect a certain area of the body, such as the back, or may spread more widely."
"One of the causes for this myalgia may be the reaction of the immune system, which releases pro-inflammatory chemicals called cytokines, which can cause the onset of body aches such as back pain." ADA adds that back pain from Covid can last a while, starting during illness or in the weeks afterward, and is one of the most common symptoms of long Covid. Chronic back pain may be explained by the coronavirus's affinity to bind to ACE2 receptors, allowing the virus to enter cells and cause damage, including in neural tissue, which may trigger chronic pain syndromes.
How to treat Covid-related back pain
For those struggling with Covid-linked back pain this winter, ADA suggests staying active, as upper back pain is often due to inactivity of back muscles. Light daily activity and stretching can help regain mobility. Over-the-counter painkillers such as ibuprofen, paracetamol, naproxen, or creams may offer temporary relief, but addressing the cause is crucial. Physiotherapy, combining massage and exercises, can help strengthen back muscles. Temperature therapy, applying heat to boost blood circulation and reduce stiffness, and lifestyle changes, including attention to ergonomics when working, driving, or lifting weights, are also recommended.
