Yes you have forgotten to mention aggravating factors, how long this has been going on and importantly what are the results of his neuro-examination i.e. reflexes and manual muscle tests. You need to confirm the presence or absence of nerve root involvement first and we need to learn about the irritability of his condition from you before we can advise further treatment options.

I thank the others in this forum to stating this already and hope everyone will begin to provide more thorough, more specific presentations. You should know the methods of clinical assessment from your training? or is it not taught so well in your country. It the later is the case, we can assist you there with a medical assessment history taking and planned approach to treatment.
