I had a partial toe amputation 26 Nov. 2nd toe, left foot. I waited a bit over 2 weeks before getting on the trainer, and the first couple rides were slow, and in the boot they provided. But it is nice that it no longer hurts... I know, different issue, but similar experiences.
Like @
BobG above, similar ankle failing. Just got an ankle AFO brace and the difference is very night and day, big positive...
