A person with ankylosing spondylitis (AS) will likely have stiffness and pain at the base of the spine and lower back.
We wish we had a short answer, but research to date has not pinpointed the cause of ankylosing spondylitis (AS).
A person with undiagnosed ankylosing spondylitis (AS) may first discuss symptoms with a primary care physician (PCP).
Ankylosing spondylitis is a type of progressive arthritis that inflames the joints of the spine. ‘Ankylos’ is Greek for stiffening of a joint, and ‘spondylo’ is Greek for the vertebra.
