In reply to john_mx:
Hey John, I had two of these little buggers repaired in an operation 10 days ago. Before the op I was climbing pretty normally but stayed off burly bouldering, roof cracks, all that stuff. I had a bit of pain from mine and couldn't eat yeasty bread for a couple of months (flat breads fine however).
The op is totally okay, felt pretty sore afterwards and beat up for about a week after - you'll definitely want to take some time off work. My surgeon said six weeks before strenuous exercise, and even then to begin again slowly, but reckoned after a few weeks gentle running would be fine. I actually don't want to climb at all right now and see no point in pushing it in the slightest.
It'd be interesting to hear from the people who've had the op already, do you guys still manage to do core exercises, hanging leg raises, that sort of thing, without any consequences?
