Ankylosing Spondylitis

This type of arthritis typically starts off making your low back and hips stiff and sore, especially in the morning. Over time, it can spread up your spine and to other joints and organs. Vertebrae and bones in your rib cage could fuse, leaving you hunched over. Young men get it more often than women, and it may run in families. Early treatment with exercise and medication helps slow the progress.
