Thanks all of you for you input, it is greatly appreciated.

I don't know why exactly I got to this stage, my other arm started showing symptoms, but has now made a full recovery on it's own.

However my left hand has had 'pins and needles' for about 6 years but only recently started to claw. I haven't given up on it yet and believe that with just the decompression surgery it can heal itself.

Thanks again.
