Yes, saw a Neurologist and they did a series of blood tests and a electrical test on my feet. They are numb. I used to have hot and cold feelings. Most of these have passed. Now it's just pain. I take pregabalin for it but it dose not seem to help. I had one goofy doctor from 2018 until 2 years ago. He left the hospital system I belong to so I found #2 in 2022. He did some more blood work that the previous doc did. Still no definitive answer as to why I have this issue. I ran into an former Transplant Coordinator and told her. She said to me, ya this can happen. So far all I know is it's possible the Tacrolimus immune surpressant I have taken since 2000 with my 1st transplant is a probable cause. It's makes me mad at times. I ask my current Transplant doctor if we can reduce the immune surpressants and he said it below the normal range already.
