It can indeed Bonnie, myself I have experienced small pitting and thickness on my 2 big toe nails. I have been able to manage it well with oil soaks on my nails. Omega 3 with a high level of epa has been making my nails and skin healthier and stronger. At the moment I have no pitting or thickness. I hope you are well! Welcome to Flaym!
Welcome to Flaym, Bonnie! Yes my nails split on my thumb especially, and the nail beds change over time. I have a few ridgy nails on the hands and a few pitted ones too that seem to come and go / move from finger to finger. I had a whole foot of psoriatic toenails for about 3 years and they looked crumbly, chalky, white and thick. Hope this helps!
