The internet is inundated with information about pain and treatments. After more than twenty years of working for ASAP and talking to hundreds of individual dealing with a variety of levels and types of pain, I have come to the conclusion that pain treatment must be individualized. What works for one person does not always work for another.
Find a pain specialist who really listens to you. Let them know what you have tried, what works and what doesn’t. Keeping a journal will help; over time we tend to forget treatments that did not work. Some treatments seem to work at first but the effects are not lasting. The important thing is not to give up and assume you have to live with the pain.
