Sure! The first time I heard about DISH was about 10 years ago when I was having severe shoulder pain. My family doctor sent me to an orthopedic doctor because he said I had some of the largest bone spurs he had ever seen. The orthopedic doctor was also somewhat puzzled, but said he faintly remembered hearing about something called DISH, and he thought I should see a rheumatologist. I had to travel to a town about 75 miles away to see the only rheumatologist he had heard about. When I saw him, he confirmed it was DISH because an x-ray of my spine showed the classic "candle dripping" look that created a solid thin line about an inch from my spine all the way down my back. He said there was nothing to be done for DISH except to try to stay active to avoid stiffening of the joints and back, and take pain medicine when necessary. He tried 10 or so pain meds without finding anything that worked very well. He said surgery to remove the bone spurs wasn't a realistic option because they would simply grow back. Over the next 6 or 7 years the pain migrated through many of my joints - spurs in my ankle caused a tear in my achilles tendon, I had a total knee replacement in which the bone eventually grew over much of the replacement as best I recall from seeing an x-ray of the knee replacement years later, I had severe pain in my hip joints and my shoulder joints. The pain has somewhat waxed and waned, and people don't understand why sometimes I can move freely while other times I am quite limited - nor do I understand it.
I have only met one other person who told me they were diagnosed with DISH, but their experience was very different from mine in that theirs affected mainly their spine, resulting in several back surgeries. My back has some spurs and random other problems, but my other joints have been my biggest problem.
I haven't really researched DISH since my original diagnosis years ago. When i tell doctors I have DISH, they generally ignore it. I would be very interested in hearing from people with the same diagnosis about their experience with it and any new research that has been done. I have never heard of any association for people with DISH or support groups because apparently it isn't very common and in fact it is just a form of osteoarthritis.
