Today Foot problems like corn foot, plantar warts, and pitted keratolysis are becoming very common. Due to modern lifestyle habits, footwear choices, and long standing hours.

What Is Corn Foot?
Corn Foot can arise from many different causes, such as wearing high heels or tight shoes, not using socks, being overweight, swelling formation, hammer toes, and foot deformities like bone spurs.
It can also be caused by pressure and constant friction from repeated movements of the foot.
The symptoms and signs of corn foot include redness the skin, heat, a firm, rough region of skin with raised bumps, flaky, dry skin, pain when walking, and restriction of daily activities due to pain.
As per the Siddha classical literature, kaalaani (corn foot) occurs due to walking over the uneven surface, and small stones and unremoved thorn pricks can induce the keratinization on the outer layer of the
skin that affects the sole to change as hard and rough.
The hardening is due to the accumulation of kabham (a combined form of earth and water), which could be normalized by the application of heat given by the uloga suttigai (heated metal probe application from corn foot ).
