Hi there,

I too badly cracked my tail bone during childbirth about 15 years ago. Although the bones technically healed, I've have recurrent problems with a "catch" feeling in my tail bone area ever since. AND I cannot sit for long periods of time without having to get up and stretch and move around. However, I find cycling hasn't been a problem so far. Being in the medial profession, I would follow what your doctor suggested and let your body tell you if and when its too much. I second the swimming and/or any other activities that would help strengthen your lower back/tailbone area without the stress. Go luck and hope your riding again soon.
