Pustular psoriasis is a rare skin disease. It makes your skin become red and painful with raised, pus-filled bumps.
People of all ages and races can get pustular psoriasis. Men get the disease as often as women do. The average age of someone who has the disease is 50. Children don't get pustular psoriasis very often, but when they do, more boys than girls get the disease. It's rare among children ages 2 to 10.
Joint symptoms that occur before, at the same time, or after skin symptoms develop.
Joint symptoms in the hands and feet.
Joint and skin symptoms that are long-lasting and return often (chronic). Symptoms can range from mild to disabling. A chronic, low-level bacterial infection or a serious joint injury in people who have psoriasis may trigger arthritis. The joint symptoms usually improve after skin symptoms improve.
Inverse psoriasis includes sores that are:
Large and red and very inflamed and dry. There is not a lot of scaling.
Commonly found in the skin folds near the armpits, under the breasts and the buttocks, in the groin area, around the anus, behind the ear, and on the face.
