Psoriasis is a chronic immune system disorder of the skin where skin cell production occurs much faster than normal. As new skin cells rapidly reach the skin’s surface and die, they leave behind raised, red areas covered with white, scaly skin. Other symptoms can include itchiness, pain, dryness and cracking of the skin, and bleeding. If present on the toenails and fingernails, you may see discoloration, pitting and a brittleness in the nail that resembles a fungal infection.
These symptoms can be tightly confined to an area, or spread to cover larger regions of the body. Psoriasis is frequently seen on the scalp, elbows, knees, palms, and the soles of the feet. Patients often mistake psoriasis with other conditions, including athlete’s foot and fungal infections. Psoriasis can also affect foot and ankle joints, causing psoriatic arthritis. However, a podiatrist will be able to diagnose this condition successfully and offer treatment aimed at relieving the symptoms.
