Your symptoms quite similar to my disease,i had been encountering this problem before i totally blackout and sent to the hospital ICU.My disease is called nerve compression and syringomyelia.When i was awake i was totally paralyzed.Just able to use my eyes to see the surroundings only.Cant even move my mouth to shriek out my voice.Just after the surgery done,i can walk back but not normally due to having spasticity issues.Still have lot of symptoms just go google it bout nerve compression,syringomyelia to check whether the symptoms is the same or not that you been suffering.

I suggest you to find a neurologist specialist and of course he might be proposing you to take a MRI for further diagnosing bout your problems you been encountered.

I m not talking nonsense here,this symptoms strikes me when i was in form1 and when i in form4 i was blackout and perforce to go through this tragic suffering road.The doctor told me that my spinal cord is compressing the nerve.He say my problem is due to congenital and of course straining will make it becoming worst.I usually spend bout 7hours a day in front the computer playing games and bending my spine.The doctor say when i m bending my spine,it will be continuously compressing my nerve and giving it massive pressure so the cavity space will become smaller and smaller.He say usually this problem will only occur in the age between 23-40+ but he say due to me putting pressure in it,the problem will be progressing rapidly.

I think this happen is because of my carelessness,i been told this problem to my parents and they wanted to bring me to consult a doctor but in the end i denied it.So all this happen is due to myself of playing computer excessively and always straining myself when doing sports.

Hope this will help you to know it better bout your problem.
