You need to get a second opinion. If you continue to have bladder dysfunction that is not normal to you then you definitely need to be undergoing some form of treatment, and treatment not just for pain as for the bladder to be affected required some type of mechanical interference. That said something to reduce compression,swelling,mm spasm may help that but you would want to see things revolving fairly quickly.
Can you work not send you to someone private? Sounds like A&E got it right by admitting you but then you got lost in the system
