Diagnosis

The doctor will ask about your symptoms and health history. A physical exam will be done. Symptoms differ for each person and change over time. This can make it hard to diagnose.

Tests that may be done include:

  • Blood tests
  • Urine tests
  • Images taken with an MRI scan
  • Skin biopsy

Treatment

There is no cure. The goal of treatment is to manage symptoms. One or more of these medicines may be used:

  • Antimalarial drugs
  • Corticosteroids
  • Drugs to suppress the immune system
  • Nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Estrogens
  • B-cell therapy
  • Blood thinners

A person will also need to prevent flare ups. This can be done with things like staying out of the sun, limiting stress, and getting enough rest.

Prevention

There are no known guidelines to prevent this health problem.
