Hello, the horizontal dips in your nails that you describe are different from the nail pitting I have. The nail pitting is like several tiny dot-shaped depressions in all fingernails.

I do not have all of the possible signs and symptoms of psoriatic arthritis, but the ones I do have are nail pitting, joint pain in fingers (they imaged my hands because of this to distinguish from osteoarthritis, and it is also not typical of RA), ankle pain, foot pain, plantar fasciitis, lower back pain, and a negative rheumatoid factor test.

Good luck with your appointment!
