I have found that strengthening my body has helped a lot with chronic pain from fibromyalgia. I know that not every chronic illness warrior is up for this type of workout. When I started I went slowly, and added more exercises as I got stronger and found a general decrease in pain. It may not work for everyone but it certainly works for me!
