Dermatologists deal with many patients who have been diagnosed with a skin disease called psoriasis. This skin condition has certain symptoms which are very common to those who suffer with it. Psoriasis can cause pain, inflammation, and scaling. Normally there is a process called cell turnover where over a period of time new skin cells grow deep under the skin and slowly come up to the surface. When an individual has psoriasis, the cells rise to the surface too quickly and then they pile up on the surface of the skin. Most of the time this is displayed on the surface as thick, red and scaly patches which can feel very sore or become itchy. Many times these unpleasant patches are discovered on the knees, elbow, or areas of the legs, face, palms, lower back, scalp or soles of the feet. However, they can also be found in other areas like toenails and fingernails, inside the mouth or in the genital area.
