Thank you so much for the reply. It's amazing how complex our medical system has become - with multiple diagnoses, or no diagnosis, even from the top specialists at Mayo (" A Place for Answers"). Yet we have to continue to "keep on keeping on" if we want to eventually find some sort of relief. Six years ago I was running 5 miles a day and enjoyed a retirement life filled with adventure, travel, and plenty of activity. It is too easy to become cynical and/or lazy to continue to seek answers. I am also the primary caregiver for my wife (late middle stages of Alzheimers). The burdon of my physical limitations compounds my ability to effectively care for my wonderful wife. Friends and family have been supportive and help out whenever they can. I am still able to drive with hand control modifications, which still gives me a sense of independence, and I will continue to fight the good fight for all of us struggling to indeed "find a place for answers." Good luck to you. And we will stay in touch. Thanks!
