I am sure that you could to a walk(even a brisk one)...check with you doctor.
Exercise is exercise.
I'm one week out from a total hysterectomy and just walked 1.8 miles yesterday...oh, it was a slow walk, but I was moving my body and getting some fresh air...actually walking is all I can do for the next 5 weeks, so I'm making the best of it. I'm looking forward to returning to complete workouts even stronger that before.
Wishing you a quick and complete recovery and finding satisfaction in the activities that you can do.
