I suddenly started having feet pain in early 2018 right after my 2nd liver transplant in 2017. One Neurologist said if was probably from taking Prograf/Tacrolimus immune surpressant since my 1st liver transplant in 2000. I had my previous transplant coordinator say it was most likely from the meds. I take 100mg Lyrica/Pregabalin twice daily. And we have medical marijuana in my state for the past 5 years so I tried it and it has helped at night when I want to fall asleep. My feet used to freeze and burn at night and I could not sleep. I signed up for the MM program and works for me. I do not use much either.
