Hi,
My name is Karen Durrant, and my middle son has a form of Cryopyrin-Asociated Periodic Syndrome (CAPS) called NOMID. I also run The NOMID Alliance.
My son used to have itchy areas when he had flares of the rash, which is the same rash for all CAPS, whether MWS, NOMID or FCAS. Most people do not feel itchy, but some have an itchy or even occasionally a burning sensation with the rash, during flares of symptoms. Please look at our website for more info, and please share the link with your nephew's famil as well. We can be of help.

Also on our site there is a downloadable pdf of a medical guidebook co-authored my leading doctors on CAPs, and myself at this link:

You may find the chart in the center spread of the booklet helpful.
I would bring the pdf with you to the doctor's visit, as you may have a form of CAPS, but you will need to get connected with a rheumatologist to help with the diagnosis. Do you have elevated C-reactive protein, ESR, or other abnormal labs? People with CAPS can have high C-reactive protein, especially during flares, but it can be normal at other times if they are not flaring in the most mild forms, such as a mild form of Familial Cold Autoinflammatory Syndrome (FCAS) that is triggered by cold or cooing temperatures. Muckle Wells and NOMID can be triggered by the cold, but often they have flares of symptoms that are frequent, and can be ever-present.
Contact me if you have more questions at site_manager@nomidalliance.net
Good luck, and I hope that you find some answers soon! The good news is that if you have CAPS, there are some wonderful and very effective medications that will change your life for the better, so there is hope for you and your nephew.
