hi, thank you for providing a brief history of your illness. Since you mentioned you have met an accident and injured the T8 level spinal column area and the neurosurgeon have decompressed it. Understanding the scene here is you are a bit annoyed by the bladder control, movement of legs and abnormal sensation. Now since its been 2 years and a much done onto for your good till date by all specialists. Help is always an inch away and doctors are always here to help. I wish to know if you have tried doing physiotherapy, if not than you should start it again. As the surgery was successful the later part was to take the regular medicines and regular physiotherapy. Bladder control exercises are known to a physiotherapist which he can teach you and brain always tends to keep learning. Now since you are looking here with some remedy for you, i would say that the doctors have done a great job till date, now you have to put a conscious effort to undergo a physiotherapy session and get yourself helped. Physiotherapy is not only about exercise but even about the deeper science behind it. All things done till now by doctors was excellent, now the body has to produce some internal medicine which has to make a help. Symptomatic help was done at the best. Now its the body turn to produce the requirements. I have seen many patients with such injuries and on the later side of the years are helped by a physiotherapist and things have turn on a positive side for many. Kindly try to undergo physiotherapy and make the body metabolic system to take the next charge. Its never easy to get back on but its never impossible to become better again. with the grace of almighty i wish you a positive outcome soon.
