Very interesting ... especially the nails information for me. About 2 months before my gallbladder attacks started, my nails went haywire. My two large toenails suddenly began ridging which is supposed to be a sign of illness and my fingernails split cracked and peeled. I just assumed it was just another sign of my Psoriasis moving on to a new level. Though I guess, both are closely related since Psoriasis can also be affected by liver health.
