The NHS explains that Peripheral Arterial Disease (PAD), also called peripheral vascular disease, occurs when fatty deposits build up in the arteries, restricting blood flow to the leg muscles.

According to the NHS website: “Many people with PAD have no symptoms. However, some develop a painful ache in their legs when they walk, which usually disappears after a few minutes’ rest. The medical term for this is ‘intermittent claudication.’

“The pain can range from mild to severe, and usually goes away after a few minutes when you rest your legs. Both legs are often affected at the same time, although the pain may be worse in one leg.”

Other symptoms to watch for include tingling, pain, burning sensations, dry or cracked skin, blisters or sores that don’t heal, fungal infections, and athlete’s foot. Thick yellow nails are also a common sign of fungal infections.

These signs might indicate a need for immediate medical attention to investigate underlying issues. Ignoring them could lead to more serious symptoms.

For heart-related conditions, these symptoms might include chest pain, heart palpitations, or shortness of breath. For diabetes, you might experience persistent fatigue, unexplained weight loss, or excessive sleepiness after meals.

Rather than waiting for these more advanced symptoms, it’s a good idea to have your feet checked by a professional.
