Cellulitis is a bacterial skin infection that can cause pain, swelling, and tenderness. It is typically caused by streptococcus and staphylococcus bacteria entering the body through a break in the skin, such as a cut or wound. While cellulitis usually affects the lower legs, it can occur anywhere on the body. If left untreated, cellulitis can lead to serious complications, including muscle pain and spasms. The infection can spread to the deeper tissues, causing muscle pain and, in some cases, muscle spasms or twitching. Early diagnosis and treatment of cellulitis with antibiotics are crucial to prevent the spread of the infection and reduce the risk of muscle pain and spasms.

What You'll Learn
Cellulitis is a bacterial skin infection
Bacteria, such as streptococcus and staphylococcus, normally live on the skin without causing harm. However, when the skin is broken, these bacteria can enter the body and cause infection. Common entry points for bacteria include recent surgical sites, cuts, puncture wounds, sores, and skin affected by athlete's foot or dermatitis. Certain factors can increase the risk of developing cellulitis, including injuries, a weakened immune system, diabetes, and poor circulation.
To prevent cellulitis, it is important to practice good hygiene and skin care. Keep any skin breaks clean and use an over-the-counter antibiotic ointment. Wash wounds daily with soap and water, and cover them with a bandage, changing it at least daily. Moisturizing the skin regularly and checking for any signs of injury or infection is also important, especially for individuals with diabetes.
If cellulitis is suspected, it is crucial to see a doctor promptly for diagnosis and treatment. Diagnosis is typically based on medical history, physical examination, and blood and skin tests to identify the type of bacteria present. Treatment includes oral, intramuscular, or intravenous antibiotics, depending on the severity of the condition. Getting treated right away can help prevent the spread of cellulitis and reduce the risk of serious complications.
While cellulitis is a bacterial skin infection, it can also spread to the tissues beneath the skin. If left untreated, the infection can spread to the bloodstream, bones, lymph system, heart, or nervous system, leading to severe and potentially life-threatening complications. Therefore, early diagnosis and treatment are crucial in managing cellulitis effectively.

It is caused by bacteria entering through a break in the skin
Cellulitis is a bacterial skin infection that can cause skin to become painful, swollen, and discoloured. It is caused by bacteria entering the body through a break in the skin, such as a cut, puncture wound, or surgical site. This break in the skin provides an entry point for bacteria, allowing them to infect the body and cause cellulitis.
Bacteria, such as streptococcus and staphylococcus, are normally present on the skin without causing any harm. However, when there is a break in the skin, these bacteria can enter and cause an infection. This is more likely to occur in individuals with weakened immune systems due to conditions such as diabetes, leukemia, or HIV/AIDS, or those with poor circulation. Certain medications can also weaken the immune system, increasing the risk of infection.
Once the bacteria enter through the break in the skin, they can cause cellulitis, which most commonly affects the lower legs and feet. However, cellulitis can occur anywhere on the body, including the face, arms, belly, and even around the eyes, mouth, or anus. It is important to note that cellulitis can also develop without any visible damage to the skin, as bacteria can enter through minor breaks or cuts that may not be easily noticeable.
If left untreated, cellulitis can lead to serious complications. The bacteria can spread to the bloodstream, causing sepsis or bacteremia, which can be life-threatening. Additionally, cellulitis can cause muscle and joint pain, making it challenging for individuals to complete their daily activities. In some cases, it may even lead to amputation, shock, or death if not treated promptly.
To prevent cellulitis, it is important to practice good hygiene and skin care. Any breaks in the skin should be cleaned immediately with antibacterial soap and water, and an antibiotic ointment should be applied to prevent bacterial entry. It is crucial to cover the wound with a bandage and change it daily to keep the area clean and protected until it is fully healed.

Symptoms include pain, swelling, redness, and tenderness
Cellulitis is a bacterial skin infection that can cause a range of symptoms, including pain, swelling, redness, and tenderness. It usually occurs when bacteria enter the body through a break in the skin, such as a cut, wound, or sore. While it can develop anywhere on the body, it most commonly affects the lower legs and feet.
Pain is a common symptom of cellulitis and can vary in intensity. It is often described as a deep and persistent pain in the affected area. The pain may worsen with movement or when pressure is applied to the affected area. In some cases, the pain may radiate to other parts of the body, such as the back or joints.
Swelling is another characteristic symptom of cellulitis. The affected area may become noticeably swollen, making it challenging to move or use the affected body part. For example, cellulitis on the hands or feet can cause difficulty in closing the hands or walking. The swelling may also be accompanied by warmth and redness in the affected area.
Redness is typically observed in cellulitis and can vary in intensity. On lighter skin tones, the affected area typically appears red or pink, while on darker skin tones, it may appear as dark brown, gray, or purple discolouration. The redness usually extends beyond the initial site of infection and spreads to the surrounding skin.
Tenderness is also a common symptom of cellulitis. The affected area may become extremely tender to touch, with even light pressure causing discomfort. This tenderness may be accompanied by warmth and swelling, further indicating the presence of cellulitis.
It is important to note that cellulitis can progress and lead to more severe conditions if left untreated. Early diagnosis and treatment are crucial to prevent the spread of infection and potential complications. If you suspect you have cellulitis, seek medical attention promptly for a proper diagnosis and treatment plan.

It can lead to serious complications if left untreated
Cellulitis is a bacterial skin infection that can cause skin to become painful, swollen, and discoloured. It is usually caused by a break in the skin, which allows bacteria to enter and infect the body. While it most commonly affects the lower leg, it can occur anywhere on the body.
If left untreated, cellulitis can lead to serious complications. The bacterial infection can spread into the bloodstream, causing sepsis, a whole-body infection that can be life-threatening. Repeated episodes of cellulitis can also cause the lymph nodes to enlarge, resulting in long-term swelling of the affected limb.
Another rare but severe complication of untreated cellulitis is necrotising fasciitis, a severe infection deep inside the body's tissues or muscles. This condition requires urgent hospital treatment. Furthermore, cellulitis may lead to gangrene, requiring surgery in severe cases.
In addition to these complications, untreated cellulitis can result in bacteremia, endocarditis, osteomyelitis, and toxic shock syndrome. In the most severe cases, cellulitis can lead to amputation, shock, or even death. Therefore, it is crucial to seek prompt medical attention and treatment for cellulitis to prevent these serious complications.

Treatment typically involves oral or intravenous antibiotics
Cellulitis is a bacterial skin infection that can become serious if left untreated. It is important to see a doctor as soon as possible for a diagnosis and treatment. Treatment for cellulitis typically involves oral or intravenous antibiotics. The type of antibiotic used will depend on the specific bacteria causing the infection, which can be identified through blood and skin samples.
Oral antibiotics are typically used for mild cases of cellulitis. Dicloxacillin, amoxicillin, and cephalexin are common choices for mild cases treated on an outpatient basis. Clindamycin or a macrolide (clarithromycin or azithromycin) can be used for patients allergic to penicillin. For nonpurulent cellulitis, cephalexin 500 mg every 6 hours is recommended. Clindamycin 300-450 mg every 6 hours is an alternative for those with severe allergies to beta-lactamase inhibitors.
Intravenous antibiotics are often used for more severe cases of cellulitis or when oral medications cannot be tolerated. Vancomycin is a common choice for severe cases, especially when treating MRSA. Daptomycin, tigecycline, ceftaroline, and linezolid are also appropriate options for parenteral antibiotics to cover MRSA. Intravenous cefazolin is recommended when the patient does not have risk factors for MRSA.
The duration of antibiotic treatment for cellulitis is typically a minimum of 5 days. However, the overall treatment duration is controversial, as shorter-duration therapy may be as effective as longer-duration therapy. Patients responding slowly to therapy may need to continue antibiotics until inflammation resolves.
