What causes heat sensation in the lower legs and soles of the feet?
Recently, my lower legs and soles have frequently felt abnormally hot, especially during sleep at night, with the sensation being more noticeable. There are no abnormal signs such as redness or swelling in the affected areas. This condition has persisted for some time. What could be causing this? Could it be a sign of some disease?

Common causes of hot sensations in the calves and soles:
1. Environmental factors: Being in a high-temperature environment or wearing thick, non-breathable clothing may cause the calves and soles to feel hot. In addition, soaking feet in water that is too hot can also lead to this sensation.
2. Intense exercise: Sudden vigorous exercise may lead to excessive lactic acid buildup in the calves and soles, resulting in a feeling of heat.
3. Mental stress: Long-term psychological stress may cause sympathetic nervous system dysfunction, leading to hot sensations in the calves and soles.
4. Allergic reactions: Individuals allergic to dust, pollen, and other allergens may experience allergic reactions, including a sensation of heat, when the calves and soles come into contact with these allergens.
5. Local circulatory abnormalities: Conditions such as varicose veins or deep vein thrombosis can impair blood return, causing heat accumulation in the affected area and resulting in a hot sensation.
6. Neurological diseases: Peripheral neuropathy, particularly common in diabetic patients, can cause abnormal sensations in the extremities, including a feeling of heat.
7. Infectious diseases: Fungal or bacterial infections of the feet can cause local inflammatory reactions, presenting as redness, swelling, heat, and pain.
