Cervical Spine - helping a friend

My friend R has had cervical problems since he was a child - he is about 40 now; one day we met for lunch; he told me that he helped someone lift boxes; as a result he could barely move his neck and had pain running down his arms; last time this happened it lasted about 2 months; that was 2 years ago. R is in tune with his body - he is a yoga teacher.
