Relax everyone. I told the nurses at rehab my program of biking 3 mi in the morning 3 at mid day and 3 in the evening pus walking and they seem fine with the program. twice a week I go to rehab and do the treadmill, stepper, and bike for an hour. I do this mainly because AFLAC pays me $130 a day to go to rehab. other wise I love my bike. Now if this numbness in my fingers and the dull pain in my shoulder blade and right tricep would go away I'd be happy. Doc seems to think it is as they said at Mayo, that it is just from the positioning during surgery and will gradually go away. Nerves probly pinched. Anyone else have this problem?
