Does hyponsis work effectively in eliminating chronic pain?

Try it, if it works then keep doing it. Not all treatments work for everyone. It's up to you and your medical providers to determine a treatment plan that works for you.

Hypnosis is not likely to eliminate chronic pain completely, but it can be a useful coping tool in helping to manage the pain better.

I don't have any particular experience with hypnosis and chronic pain but I have heard that it has been helpful for other people I know. More or less as a distraction but not a cure. Hypnosis works in the sense of making you concentrate on something else when you are feeling the pain at a high intensity. I find it more helpful to take a warm bath. Hypnosis works in a sense to help you concentrate on something other the pain and helps you form another habit instead of focusing on the pain itslef. Try using breathing as a coping mechanism
