NHS GP Issues Critical Alert Over 'Flu-Like' Skin Infection Symptoms
A well-known television doctor has delivered an urgent public health warning, emphasising that a common skin infection can present with flu-like symptoms but may escalate into a life-threatening condition if not treated promptly. Dr Ranj Singh, a regular contributor to BBC Morning Live, stressed the importance of recognising the signs of cellulitis and seeking immediate medical attention when necessary.
Understanding Cellulitis: A Serious Skin Infection
Cellulitis is a bacterial skin infection that affects the deeper layers of the skin and subcutaneous tissue. Contrary to common misconception, it is entirely unrelated to cellulite. The condition requires antibiotic treatment, and the NHS cautions that it can become severe without rapid intervention.
Dr Ranj explained that cellulitis typically causes the skin to become painful, hot, and inflamed. "It can look completely different on different types of skin," he noted. "On lighter skin, it often appears red, but on darker, black, and brown skin tones, it may present as slight discolouration. Blisters can also develop."
Symptoms and Presentation
The doctor highlighted that cellulitis can produce associated systemic symptoms. "You might feel flu-like, with swollen and painful glands," he said. "Occasionally, it can become life-threatening if it's spreading and worsening, though most people recover with proper treatment."
While cellulitis is frequently found on the legs, it can affect any body part. "You might get cellulitis on your hands, causing fingers or the entire hand to swell. It can also occur on feet, particularly near toes, and even in and around the eye," Dr Ranj detailed. He added a crucial diagnostic point: typically, only one leg is affected. "If both legs are involved, it may indicate another underlying issue that requires investigation."
When to Seek Emergency Care
Dr Ranj issued a stark warning regarding specific symptoms that necessitate immediate emergency action. If you suspect cellulitis and cannot secure a GP appointment, he advises calling 999 if you experience any of the following alongside the infection:
- A very high temperature
- Feeling hot and shivery
- Dizziness or faintness
- A fast heartbeat or rapid breathing
- Cold, clammy, or pale skin
- Unresponsiveness or loss of consciousness
- Confusion or disorientation
- Purple patches on the skin
These signs may indicate sepsis, a potentially fatal complication that requires urgent medical care. The doctor emphasised that cellulitis around the eye constitutes a particular medical emergency, as it can be "dangerous for your vision." Symptoms include redness in the whites of the eyes or the eyeball protruding. While peri-orbital cellulitis (around the eye) is more common and generally less severe, it still requires professional assessment to prevent spread.
Causes and Risk Factors
Dr Ranj clarified that cellulitis is most commonly caused by a bacterial infection. Bacteria enter the deep skin layers through breaks in the skin barrier, such as cuts, insect bites, cracked skin from infections, or dryness from conditions like eczema. "When the barrier breaks down, bacteria can get in and cause cellulitis," he explained. Individuals susceptible to such issues face higher risk, sometimes without noticing a visible wound.
The infection is not contagious from person to person. However, certain factors increase vulnerability:
- Poor circulation in limbs, often associated with being overweight
- Difficulty moving around
- A weakened immune system due to treatments like chemotherapy or conditions like diabetes
- Lymphoedema, which causes fluid accumulation under the skin
- Injecting drugs
- Surgical wounds
- A previous history of cellulitis
Treatment and Recovery
Treatment for cellulitis primarily involves antibiotics. Dr Ranj stated that these typically take a couple of days to begin working, with full recovery usually occurring within 7 to 10 days for milder cases. "For serious infections or individuals with underlying health conditions, intravenous antibiotics administered in a hospital setting may be necessary," he added.
The doctor's comments, originally made during a television appearance last year, remain critically relevant. He concluded with a firm reminder: "If cellulitis is not treated properly, it can worsen and sometimes become serious. Recognising the signs and acting quickly is essential."
