Lizzie749, you mentioned something that got my attention. Back when I was diagnosed with seronegative spondyloarthropathy in 1990, my rheumatologist also mention that time would tell what category I would fall into. She noted in her records that I have no pitting in my nails, but I have very deep, long, verticle ridges. She thought that was interesting. I have always wondered about that too, since my nails have been like that as long as I can remember.
After all these years, my spondyloarthropathy still hasn't chosen to go down one specific road. At this point, I've decided that it likes being a diverse and unpredictable traveler.
