Psoriasis on the foot
Psoriasis of the feet is a problem that often affects people with diabetes, but might strike anyone from early adulthood onwards.
Psoriasis is a skin disorder where small red, crusty areas appear on the skin covered in silver-coloured scales, and may also affect fingernails and toenails. Psoriasis is not infectious, but it is a long-lasting condition that requires treatment to improve symptoms and the appearance of affected skin.
Psoriasis is caused by certain skin cells growing too quickly, resulting in a build-up of immature cells on the skin surface, which then die and flake off. The result is an itchy, sore patch that may bleed and spread. Research has shown that psoriasis may flare up due to triggers such as stress, hormonal changes or an adverse reaction to some medications.
Psoriasis may also affect toenails, creating small pits or dents, and in some cases, causing the nail to grow abnormally and separate from the nail bed.
