Psoriasis consists of raised red patches that are covered with light-colored scales on the lower back, most commonly on the knees and elbows, or on the scalp. Other varieties of psoriasis can cause small red spots, white pustules, smooth red lesions where the skin folds, and widespread redness, itching, and pain.
What Causes Psoriasis?
Scientific research indicates that psoriasis may be a disorder that causes our immune system to over-react and rapidly accelerate the production of skin cells. Instead of growing normally and being replaced every month, the cells may mature in as little as three days and pile up on the surface of the skin. Genetics may also play a role, and injuries to the skin, stress, sunburn trauma and other events may lead to an outbreak as well.
What Are The Symptoms of Psoriasis?
In addition to the visible signs listed above, psoriasis can cause discomfort (itching or pain) but very mild cases may remain unnoticed. Embarrassment about appearance is also a common reason for treatment.
Types of Psoriasis
People can suffer from different types of psoriasis. These can be listed as follows:
- Nail psoriasis: This condition affects the toenails and fingernails, causing discoloration, abnormal nail growth and pitting. In some cases, the affected nail either gets separated from the nail bed or it crumbles.
- Plaque Psoriasis: This is one of the most common psoriasis types, causing red, dry and raised patches on the skin covered with scales. Their number may vary from one person to another and can be either itchy or tender. Plaque psoriasis appears on the back, elbows, scalp and knees.
- Pustular Psoriasis: This is a rare form of psoriasis that causes scaly and red skin with tiny pus-filled lesions in widespread patches on the feet soles or palms.
- Guttate Psoriasis: This type of psoriasis starts quite early during young adulthood or childhood. It causes red and small drop-shaped spots or lesions to appear on the limbs and torso. The most common triggers of this psoriasis include strep throat, respiratory infections, skin injuries, stress, tonsillitis, or taking beta-blocker and anti-malarial medications.
- Inverse Psoriasis: This condition causes bright and shiny red lesions to appear on the skin folds such as the groin, under the breasts or the armpit. The condition often gets worsened with sweating and friction. This psoriasis condition is triggered mainly by fungal infections.
- Erythrodermic Psoriasis: This is one of the least common types of psoriasis affecting the general public. It covers the entire body with a peeling red rash that can cause intense burning or itching sensations.
- Psoriatric Arthritis: This condition causes painful swollen joints similar to arthritis. In fact, in most cases, this is the only symptom observed. This condition causes nail changes with symptoms ranging from mild and severe. It can cause progressive joint damage and stiffness in the affected joint, which then progresses to permanent damage of joints, in some cases.
