Have you ever done any meditation? Lay flat (no pillow) in a semi dark room. Candlelight would be good. Or maybe even a nice bath with lavender which is calming. Close your eyes and just don't think of anything but your breath going in and out, in and out. Focus on your breath and your beating heart. Then pay attention to your core. Feel it from the inside. Is it good? Does it hurt? Slowly move out to your extremities. Visualize the pain moving out to your extremities. Push the pain out of your fingers, then your toes, then out the top of your head. As you do this tell your self that you love your body, that your body is strong, that your body feels good.
Positive self talk is an important part of healing. Like prayer, if you believe it, then it will help.
My mom has had rheumatoid arthritis for 40 years. She's had a lot of pain and tolerates tremendous pain with low doses of pain medication (took only Motrin after ankle replacement!) Here is her recipe: chocolate, laughter, and sex (self stimulation works just fine.) All of these produce endorphins that reduce pain.
I hope you find relief soon! This disease sucks!
