Hi @kzeiss, I think it's bad enough having to deal with psoriasis but on your hands and fingers has to be the pits. There is another discussion where members are talking about treatments that you might find helpful.
--- Psoriasis: What treatment helps?: https://connect.mayoclinic.org/discussion/psoriasis-1/.

I also found a reference on the National Psoriasis Foundation site discussing the difficulties when psoriasis is on the hands and feet that might be helpful.
--- When Psoriatic Disease Strikes the Hands and Feet: https://www.psoriasis.org/advance/when-psoriatic-disease-strikes-the-hands-and-feet/.

It's great to hear you have a doctor that is working with you on seeking a treatment that helps. Have you done any reading on the National Psoriasis Foundation website specifically when psoriasis is on the hands and feet?
