Over the last couple of months I've had a few episodes of lower abdominal pain, and am in line to be investigated for a likely kidney stone. Two of the episode have started on Thursday morning, i.e. the morning after my regular evening club run. I was wondering if anyone has had experience of this problem, and is it likely that cycling could bring on a bout of renal colic by causing the stone to move around. Should I get into the gym until the stone gets sorted?
