Will the pain ever go away completely?

Depends: It depends on location of pain and primarily its cause. If the cause is curable or manageable, you may have complete resolution of pain, if not, then .....

Too vague: Not sure what kind of pain, where the pain is located, does it come and go, whom you have seen. I would write up a pain diary. Each day, write down what you eat, how you feel, rate your pain from 0-10, how it changes throughout the day, etc. Then talk to your doctor about going to a pain clinic. Hopefully you can be helped!
