Sadly, my daughter was prescribed a medication that tears up one’s esophagus, so she is in quite a bit of pain and we have had a couple of ER visits. She is getting better, slowly.
One of the things that I have done to help in the matter is I have taught her the use of her imagination as a means of controlling pain. Essentially what I asked her to do was to imagine turning a dimmer switch down on the pain. As with all things related to hypnosis, it wasn’t a cure, but it was a good treatment–she was calmer and in less pain after doing that.
There was an article in the WSJ about the use of meditation, hypnosis, and other methods for handling pain, which I would advise for you: http://online.wsj.com/article/SB10001424052702304760604576428151831584880.html#articleTabs%3Darticle. Another good article is: http://www.webmd.com/pain-management/hypnosis-meditation-and-relaxation-for-pain-treatment, although I disagree with the conclusion that it cannot be used with people with a history of trauma–it should be done by someone who has had sufficient training in hypnosis and who has a license in a healing profession.
As in all things medical, don’t try this without consulting with your doctor.
