Has anyone had problems with the tendons in their hands causing stiffness and trigger fingers especially at night time?

I'm having this problem and has occurred since my transplant a year ago (today). Hands stiffen up at night and have had at least 3 fingers triggering. Had a couple of steroid injections in both hands a few months back which seemed to have fixed things, but it has come back and now need an operation to widen the tunnel at the base of the finger so the tendon moves freely. I'm on a range of medicines, including Advagraf and Myfenax.
