Danger of paralysis with herniated disk & TMS symptoms?

3 weeks ago I started feeling leg pain which intensified to the point of going to the ER.
Did MRI and the doctor showed me that I have a herniated disk.
Had intense pains for 3 days and then it subsided very quickly.
Now my right leg is still a little numb and feels like the muscles are cramped when I move.
While resting at home, I read the Healing Back Pain book and I am a textbook TMS case.

My question is this:
The doctor said that the nerve blockage caused by a disk hernia can be so bad as to fully paralyze a person.
Are these two different conditions?
Can TMS cause full paralysis and loss of bladder control?
Obviously, the doctor has never heard of TMS, so how can I differentiate between real structural risk and TMS?
