I had spinal fusion surgery in 09'. would it be a good idea to get my hardware out because of pain? i am now only 22 and don't want to live like this.

Probably not: Depends on the scenario, but hardware removal often does nothing to improve the back pain. In other words, persistent pain is often not due to the hardware itself, but instead due to problems at another level(s) in the spine, or possibly failure of fusion. You should see a spine surgeon for further evaluation (i.e. x-rays, CT vs MRI) to nail down a diagnosis for your ongoing pain.

Depends: It really depends on your specific case. In general, hardware itself in a well healed fusion usually does not cause pain and so simply going in and removing your hardware may not be any benefit. The bigger and more appropriate question is what is the specific cause of your pain; and then based upon that diagnosis, what is the cause of your pain.
