One thing I do not understand fully yet is the rate that nerves heal. I understand that generally they heal at 1mm a day, what I do not get is - Do you have to wait for a nerve to reach the affected area of your body, or do you just have to wait for the nerve to heal the damaged part, and then the rest of the nerve automatically starts working.
For example, if you have nerve root damage, and a lesion that is about 10mm away from the spine. Your arm is not working. Does that mean, in 10 days the lesion would be fixed and your arm would work OR does it mean that the nerve has to grow over that lesion and then work its way down your arm at 1mm a day to renew all the nerve below that initial damaged part?
I hope that makes sense, its something i cant work out myself.
