Pustular Psoriasis Symptoms

In the generalized type, the skin is initially fiery red and tender. You may have symptoms such as headache, fever, chills, joint pain, a feeling of general discomfort or uneasiness, decreased appetite, and nausea. Within hours, you may see clusters of pustules.
 
The most common places these pustules appear are the anal and genital area and bends and folds in your skin. Pustules may appear on the face, but this is unusual. Pustules can appear on the tongue, which may make it difficult to swallow. They can also occur under your nails and cause your nails to come off.
 
Within a day, the pustules fuse together and form "lakes" of pus that dry and peel off in sheets. The skin underneath is a smooth reddish surface, on which new pustules can appear. These episodes of pustules appearing, fusing and peeling, and reappearing can last for days to weeks. They can make you uncomfortable and exhausted. In 2-3 months, a phase involving hair loss can occur.  
 
Once the pustules improve, most of your other symptoms (such as headache and fever) will usually disappear. However, in some people, the skin may remain bright red, and skin symptoms of nonpustular psoriasis may continue.
 
The ring-shaped type is more common in young children. This type tends to be subacute or chronic, and the symptoms are less severe than in the generalized type. Ring-shaped plaques (elevated areas) appear and are often recurrent. Pustules may appear at the edges of the ring. These areas of skin symptoms appear mostly on the trunk but also on the arms and legs. The edges expand, and the center heals. Other symptoms are either absent or mild.
 
The juvenile, or infantile, type of pustular psoriasis is usually mild. Other symptoms besides skin symptoms are seldom present. The condition often resolves on its own.

Pustular psoriasis of the palms and soles is usually chronic and may be associated with bone or joint inflammation. The palms or soles are red with white or yellow pustules.
