there is essentially no necessary difference.
Technically, neurogenic means irritation or disease of the nerves.
Mechanical, if causing nerve irritation or disease of the nerves, is also neurogenic, with a mechanical cause.
So, the mechanical with neurogenic is simply a more accurate description in this case.
neurogenic alone would be from nerve disease with no muscle, ligament or disc problems, which is extremely rare.
