TV Doctor Issues Critical Warning About Foot Symptoms
Dr Amir Khan, a prominent NHS GP and television personality, has issued an urgent health warning regarding symptoms that manifest in the feet. He emphasised that certain foot conditions should never be dismissed, as they could be indicators of serious underlying health problems requiring immediate medical attention.
Cold Feet and Circulatory Concerns
Dr Khan explained that experiencing unusually cold feet or toes might signal circulatory issues, specifically a condition known as peripheral vascular disease. This disorder involves problems with the small blood vessels in the feet, restricting blood flow. It can be associated with poorly controlled diabetes, high cholesterol levels, and is more prevalent among smokers.
Burning Sensations and Nerve Damage
The doctor highlighted that burning or tingling pain in the feet could indicate peripheral neuropathy, a nerve damage condition. This is particularly common in individuals with unmanaged diabetes but can also result from low B12 or folic acid levels, thyroid disease, excessive alcohol consumption, or certain medications.
According to NHS information, peripheral neuropathy affects the nerves in extremities like hands and feet, with symptoms varying based on which nerves are damaged. In the United Kingdom, it is estimated that nearly one in ten people aged 55 or older suffer from this condition. Regular check-ups are crucial for high-risk groups, including diabetics.
Foot Pain and Structural Issues
Dr Khan continued by addressing pain in the sole of the foot during walking, especially without a remembered injury. This could point to plantar fasciitis, an inflammation of the tissue beneath the foot causing sharp, stabbing heel pain. Alternatively, it might indicate a stress fracture from overuse, arthritis, or an inflamed tendon.
The Royal Berkshire NHS Foundation Trust notes that plantar fasciitis affects 10 to 15 percent of people, occurring at any age but most commonly in those over 40. While approximately 90 percent of cases respond well to conservative treatment, persistent micro-tears can lead to long-term discomfort.
Slow-Healing Sores and Swelling
Dr Khan stressed the importance of seeking medical evaluation for sores or ulcers on the feet that do not heal properly. He warned that such wounds could indicate skin cancers or be exacerbated by poor circulation, uncontrolled diabetes, or increased infection risk due to impaired healing processes.
Regarding swollen feet, the doctor noted that while common from prolonged standing or summer heat, swelling can also signal liver, kidney, or heart problems. Other contributing factors include obesity, pregnancy, certain medications, arthritis, infections, or blood clots, especially if swelling is one-sided.
Dr Khan concluded with a firm recommendation: "Always get unexplained swelling checked. In fact, any symptoms with your feet that's unexplained and going on, get them checked." His advice underscores the critical role feet play in revealing broader health issues, urging vigilance and prompt consultation with healthcare professionals.
