Check CAPS symptoms

Find out if your symptoms indicate CAPS.

People with Muckle-Wells Syndrome (MWS) usually have symptoms at birth. Occasionally, symptoms may start later in childhood.

Symptoms of MWS, which is a subtype of Cryopyrin-Associated Periodic Syndromes (CAPS), often begin after a person is exposed to cold temperatures or when the body is tired. They can also occur without any obvious reason.

Duration of MWS symptoms

There may be days when some MWS symptoms are not felt.

When someone does have symptoms, they tend to get worse throughout the day. While some symptoms can last longer, MWS symptoms typically last 1 to 2 days.

Discussing the MWS diagnosis

You may not know you have MWS disorder, but your symptoms will make you aware that something is wrong. If you suspect you may have this genetic syndrome, you should talk with your doctor.
