And back pain can be caused by activities away from work that are not related. For example, I had to give up golf because of back pain, I have a degenerative disc in my neck (heredity issue - I was built wrong w/ no warranty) and it causes mucho pain at times in strange place that nervous system we have is very complicated. - won't go under the knife - just physical therapy and home exercise works - don't want to risk a slip of the scapulae by Dr. Shaky Hands for a procedure that "might" comeback - but PT ain't cheap
Some people try to get their employers insurance to cover the cost of treatments.
