Any drug that provides long-term relief from debilitating pain, but does not cure the underlying condition, would be addictive. Regardless of whether a physical addiction was developed, your body would develop a need for that drug to function properly. It's not necessarily a problem, but important to recognize that drugs that make you feel better are inherently addictive. We don't want to go down the same road as we did with opioids.
If you have a limp, and a cane helps you walk better, and you use that cane for the next 10 years, then your walk and gait conform to the cane, making it more difficult to walk without it. Thus, your body has developed an addiction to the cane.
I could be mis-construing the definition of addiction though. More like dependency or habit? Does an addiction necessarily need to have a negative impact on your life in order to be characterized as such? Am I addicted to coffee?
