There's nothing minor about even a minor spinal cord injury. If you think you've suffered an injury to your spinal cord, visit a physician -- not a chiropractor -- immediately, and get yourself checked out thoroughly. If you wait, it could get worse -- and you could lose some of your mobility.
Although chiropractors can be helpful, it's not a good idea to let anyone manipulate your spine if you think you've got a spinal cord injury of any kind. Despite their good intentions, a chiropractor can cause even more injury than before, especially if they work on you too vigorously.
