angela Could it be Psoriasis
Psoriasis is a common skin disorder that produces thick red plaques covered with silvery scales. The most common areas affected are the scalp, elbows, knees, and lower back, although any skin surface may be involved. It can also occur in the nails and body folds.
Psoriasis is not contagious and cannot be passed from person to person, but it can occur in members of the same family.
Psoriasis usually begins in early adulthood or later in life. In most people, the rash is limited to a few patches of skin; in severe cases, it can cover large areas of the body. The rash can heal and come back throughout a person's life.
What Are the Symptoms of Psoriasis?
Psoriasis starts as small red bumps, which enlarge and become scaly. The skin appears thick, but bleeds easily if the scales are picked or rubbed off.
In addition, the rash may produce:
Itching
Pitted, cracked, crumbly, or loose nails
How Can I Find Out if I Have Psoriasis?
If you have a rash that is not healing, contact your doctor. He or she can evaluate the rash to determine if it is psoriasis.
What Causes Psoriasis?
The exact cause of psoriasis is unknown, but it is believed that a combination of factors contributes to the development of the disease.
An abnormality in the immune system causes inflammation in the skin, triggering new skin cells to develop too quickly. Normally, skin cells are replaced every 28 to 30 days. With psoriasis, new cells grow and move to the surface of the skin every three to four days. The buildup of old cells being replaced by new cells creates the silver scales of psoriasis.
What Causes Psoriasis Outbreaks?
No one knows what causes psoriasis outbreaks. The severity and frequency of outbreaks vary with each person. Outbreaks may be triggered by:
Skin injury (for example, cuts, scrapes or surgery)
Emotional stress
Strep infections
