Cellulitis is a common bacterial skin infection that can cause muscle weakness. It is characterised by swelling, pain, redness, and warmth in the affected area. While cellulitis can occur anywhere on the body, it most commonly affects the lower legs and feet. The infection is typically caused by bacteria entering through breaks in the skin, such as cuts, wounds, insect bites, or skin conditions like athlete's foot. If left untreated, cellulitis can spread to deeper tissues, the lymph nodes, and the bloodstream, leading to serious complications. Early diagnosis and treatment with antibiotics are crucial to prevent the spread of infection and potential muscle weakness.

Cellulitis is a bacterial skin infection
While cellulitis can occur anywhere on the body, it most commonly affects the lower legs, with around 14 million cases in the United States per year. It usually only affects one leg and can cause difficulty walking. If left untreated, cellulitis can spread to deeper tissues, the lymph nodes, and the bloodstream, leading to serious complications such as sepsis.
The risk factors for developing cellulitis include skin wounds, weakened immune systems, skin conditions, long-term swelling of the legs or arms (lymphedema), history of cellulitis, and obesity. Certain conditions, such as diabetes, leukemia, HIV/AIDS, and vascular disease, can also increase the risk by weakening the immune system or affecting circulation.
To prevent cellulitis, it is important to practice good hygiene and take care of the skin by moisturising regularly and cleaning any wounds with water and antibacterial soap. If cellulitis is suspected, it is crucial to seek medical attention promptly, as early diagnosis and treatment with antibiotics are essential for a successful recovery.

It can cause muscle weakness and pain
Cellulitis is a bacterial skin infection that causes swelling and pain. It most commonly affects the lower legs and feet, but it can occur anywhere on the body. The condition is characterised by redness, tenderness, and warmth in the affected area. While cellulitis is typically not contagious, it can be serious if left untreated.
Cellulitis can cause muscle weakness and pain. The infection can spread to the bloodstream, leading to a serious whole-body infection called sepsis. This can result in muscle weakness and pain throughout the body. In addition, cellulitis can cause flu-like symptoms, including fever, chills, sweats, body aches, and fatigue, all of which can contribute to muscle weakness.
The pain and swelling associated with cellulitis can also make it difficult for people to complete their daily activities and may contribute to muscle weakness. The infection usually appears as a small spot on the skin that quickly spreads to cover a much larger area. This spread can result in increased pain and swelling, further impacting an individual's ability to move and use their muscles.
In some rare cases, cellulitis can lead to a severe infection deep inside the body's tissues or muscles, called necrotising fasciitis. This complication requires urgent hospital treatment.
It is important to seek medical attention if cellulitis is suspected, especially if it is the first time experiencing the condition. Antibiotics are typically prescribed to treat cellulitis, and most people make a full recovery.

It is often caused by skin wounds
Cellulitis is a bacterial skin infection that can occur anywhere on the body but is most common on the lower legs. It is caused by bacteria entering the body through a break in the skin. This break in the skin may be due to a cut, fracture, burn, scrape, insect bite, surgery, or another type of injury. The skin may also be weakened by certain skin conditions, such as eczema, athlete's foot, or shingles, which can create an entry point for bacteria.
The risk of developing cellulitis is higher for people with skin wounds, as these provide an easy entry point for bacteria. If you have a skin wound, it is important to practice good hygiene to prevent cellulitis. This includes cleaning any wounds with water and antibacterial soap and covering them with a clean bandage.
In addition to skin wounds, other risk factors for cellulitis include a weakened immune system, obesity, diabetes, vascular disease, and poor circulation. Having had cellulitis before also increases the risk of getting it again.
The symptoms of cellulitis include skin that is swollen, painful, and warm to the touch. There may also be redness or skin discolouration, blisters, and tenderness. If cellulitis is suspected, it is important to seek medical attention promptly, as the condition can become serious if left untreated. Antibiotics are typically prescribed to treat cellulitis, and most people make a full recovery.

It can spread to the bloodstream
Cellulitis is a common skin condition that can occur anywhere on the body but is most prevalent on the lower leg. It is a bacterial infection of the skin and the tissue beneath the skin. It is usually caused by bacteria entering through a break in the skin, such as a cut, fracture, insect bite, or surgery. While cellulitis is not typically contagious, it can be contracted through skin-to-skin contact with an infected person's open wound.
If left untreated, cellulitis can spread from the skin to the underlying tissues, lymph nodes, and bloodstream. This can lead to a serious whole-body infection called sepsis or bacteremia. The spread of cellulitis to the bloodstream is known as septicaemia. This condition can be life-threatening and requires urgent medical attention.
The signs and symptoms of cellulitis vary but typically include redness or skin discolouration, swelling, warmth, tenderness, and pain. Flu-like symptoms such as fever, chills, sweats, body aches, and fatigue may also be present. These symptoms can make it challenging to walk or perform daily activities.
It is important to seek medical attention promptly if cellulitis is suspected. A healthcare provider will examine the affected area and may perform additional tests, such as blood tests, to confirm the diagnosis and determine the extent of the infection. Antibiotics are the standard treatment for cellulitis, and most people make a full recovery.
To prevent cellulitis, it is essential to practise good hygiene and take care of the skin. Wounds should be cleaned with water and antibacterial soap and covered with clean bandages. Additionally, moisturising the skin regularly and wearing appropriate protective gear during activities such as gardening can help reduce the risk of developing cellulitis.

Treatment includes antibiotics and home care
Cellulitis is a bacterial skin infection that can occur anywhere on the body but most commonly affects the lower leg. It is usually treated with a course of antibiotics, which should be taken for as long as your healthcare professional directs, typically 5 to 10 days. It is important to finish the full course of antibiotics, even after symptoms disappear, which typically occurs a few days after starting treatment. More serious cases may require intravenous antibiotics.
In addition to antibiotics, home care treatments can help speed up the healing process and make you more comfortable. These include:
- Applying a warm compress to the affected area to help reduce swelling and other symptoms.
- Elevating the affected area to lower blood pressure in the area's blood vessels and improve blood flow.
- Using compression wraps or stockings to reduce swelling and improve blood flow. It is important not to wrap the affected area too tightly, as this can cut off circulation. The wrap or stocking should be removed at least twice a day for 10 to 15 minutes.
- Taking over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, or naproxen to reduce pain and inflammation. However, it is important to check with your healthcare provider before taking NSAIDs, as not everyone can take them.
To prevent cellulitis, it is important to practice good hygiene and keep your legs moisturized with an unperfumed moisturizer. Wounds should be cleaned with water and antibacterial soap and covered with a clean bandage to reduce the risk of infection.
