Thanks tntlamb. I suppose I would fall into the "peripheral" category. I do have lower back/butt pain and my neck crackles when I turn my head, but I also have pain in my knees, wrists, elbows, various fingers, sometimes ankles and sometimes ribs. My rheumy is still refining my diagnosis - she said it's most likely AS, but it's the "female" form, referring to all the peripheral involvement and the fact that my SI joints are still open.
