i have problems walking first thing in the morning, right before i go to sleep, and when im sick, pretty much when im tired. my past history includes POTS syndrome and an injury to a nerve in my ankle last year. The walking can be described as a crouching gait and problems picking up my feet . It goes away when im not tired. I will bring it up with my neuro when I next see him, but that isn t until may, and i m curious.
