What would be the reason and treatment options for a debilitating back pain that is not responding to pain killers, muscle relaxers, icing, and rest?

I will advise that you seek consultation with the spine specialist.

Most likely MRI and dynamic X-rays of the back will need to be done before further treatment is suggested.
