I, too, thought it would be biofeedback or self-hypnosis. But, instead, it was an hour interview with a doctor who specialized in pain management, both from a psychological and physical viewpoint. I have had anklyosing spondylitis, a form of rhematoid arthritis, since my early twenties.
The doctor took a very thorough history and then essentially fine-tuned the medications and treatment I was on.
At age 77, I had no further tolerance for oral, or rectal, anti-inflammatory medications and their attendant acid-suppressors, so I was advised to use only anti-inflammatory creams and only when necessary. Tylenol, 500 mgs. every 4 hours, not to exceed 4000 mgs. per day, kept the pain in check.
The use of physio and excercise, including water exercises as prescribed by the pysiotherapist, was encouraged.
A characteristic of ankylosing spondylitis is that the pain increases during the night. I never got a good night's sleep, which increased the pain, which increased the lack of sleep the following night. Breaking that cycle with a very low dose of the anti-depressent Trazodone at bedtime was the crux of solving my problem. (One of the side effects of Trazodone is sleepiness, and the sleep produced is close to a natural one.) I take 1300 mgs. of long-acting Tylenol, plus 25 mgs.of Trazodone, at bedtime.
Once I got the pain under control, I now take approx. 3000 mgs. of Tylenol per 24 hours. plus 25 mgs. Trazodone. I exercise 3 times a week at the YWCA, which has equipment that you can increase or decrease in resistance to within a pound or two, thus avoid injuring yourself. The swimming pool water is warm and there is a hot pool.
I didn't mean to go on and on, but sometimes the truth is in the details.
