My pain management dr suggests a pain pump foru chronic back pain what do you think?

Maybe: All options should be evaluated with your doctor, in order to make the decision that's right for you. Pumps are usually a choice that is made when oral medication has been unsuccessful.

It is an option but : This type of treatment is typically indicated for end stage cancer pain control. Other alternatives could include the use of a spinal cord stimulation if you have failed all other courses of treatment and there is no viable other surgical option for treating your chronic back pain.

Last resort: It should only be a last resort option if nothing else helps. You have to get the pump refilled monthly or every other month and there is a chance for infection with every refill. If you miss a refill you can go into life threatening withdrawal so it limits possible travel. There may be other options like spinal cord stimulators, chronic pain rehabilitation, cognitive therapy... Good luck.
