Dear BeeLady: Gee, thanks for showing to a board certified urologist. I'm 44 years old and do not have any loss of muscle control or sensation. On the day of the problem, it wasn't hot, I didn't sweat that much and yes, I had the need and sensation to urinate but could not. They put me on macrodantin and I was to go back the next day if the emptying didn't improve. It did improve (but not yet 100%), so I have not yet gone back to the MD. As far as GI problems, yes, I do have GI problems. I had an appendectomy and right colon resection (12 inches of colon removed) in 1999. But, I've never had any bowel/bladder problems since I have been actively biking for 2 years. Sunday was the first problem.
