I have OPLL. I'm not sure about DISH. I don't remember it being mentioned, but I might have been in a fog. I went from thinking I had a minor but annoying shoulder problem to finding out I had a rare condition that required almost immediate surgery to avoid becoming quadriplegic. I have it at several levels, but the worst is c4-c5 where the arm nerves come out. I will have surgery next week, finally, after a couple of tense weeks getting clearance from the cardiologist because of aortic stenosis, which is caused by calcification of the valve. It's not clear now whether I was born with a bicuspid valve which was worsened by calcification, or if it was normal and then fused with calcification. I am going to an endocrinologist at the end of the month to see if all this calcification has a root cause. I have found very few people on line with this disease, but there are a few at Inspire.com. Check them out. There are some encouraging reports about recovery.
