Hello @rsb and welcome to Mayo Clinic Connect. Thank you for sharing your history with your Post Polio Syndrome and the hypothesis with regard to your potential for increasing pain. I understand you are pain-free, currently, during the day, however, you suffer from foot and leg pain at night.
I can see you are interested in connecting with members to discuss this more. In my search for members who have mentioned this very syndrome, I have come across @joyhead1 and @bruce0712 in hopes they may have some experiences to share with you.
What have you tried for your pain at night so far?
