Pennylucky,
I insist that a neural tissue problem is your case. Sensation alterations along with inability to control your muscles indicates this. Since you had an accident and inability to walk for a while, then it's indicative of a spinal cord damage. What you might need is a therapy scheme of improving motor control of your body. It is possible to improve motor control even though prognosis is not really good for neural tissue full recovery. That means that your body can compensate for the lack of sensory and motor function by 'activating' and educating other parts of it.
