the brain is the lifeline to the body and an injury can affect us all in many different way. I had urinary problems that went away with time. I would do what mark in Idaho suggested and maybe see a gastro doctor and explain what happened. I'm years into my injury and a massage still hurts me. let your doctor know what you feel and if he doesn't help tell your lawyer you want a different doctor. you are very early in recovery so be patient although I know it is hard. and feel free to ask anythibg you want.
