What are non-addictive substitutes for pain medications?

NSAID's which are used for both pain and inflammation but can be uspeting to the stomach and gastrointestinal tract. There is also a medication called tramadol which is also used for pain. I am on Tramadol and it *does* contain opiates. Tramadol falls into a milder version of a controlled pain medication, but it does contain opiate's.
