Possibly. For example, there are several cases in the medical literature of patients with longstanding lower limb CRPS who have problems with the function of their bladder and bowel and also have abdominal pain. Even though it may start at one site like the foot, CRPS is a chronic condition that involves the entire nervous system. It often causes the autonomic nervous system (the nervous system that looks after internal organs) to react and not function properly like they should.
