Cyclosporine acitretin and psa

Been on cyclosporine for nearly 2 years, other than hating hiding in the shade (was and still am a sun lover) its been great, I sleep, im in no pain I barely itch , hands and feet healed, only occasionally flare since they reduced my dose to 150 after losing weight. Two years coming up and they want to switch me to acitretin and im terrified.. The thought of peeling skin again or my face and neck flaring again (had dermatitis too) seems unbearable. Also I have arthritis with achillies and plantar facilitis pain and knee pain below and sides. History of tennis elbow and nerve issues too. Never had an xray as they said there's no heat on joints and had negative ra blood so they said its OA and separated the issues but Dermatology said it could still be psa. I know cyclosporine helps psa but acitretin doesn't so also worried that joint pain may get worse. Can anyone relate to change in meds side effects and benefits or early psa/oa symptoms
