@smdawson540 I wish you all the best. I experience exercise limitations and am currently moderating at 10 minutes elliptical (for leg strength not cardio fitness), 6 squats, and 6 pushups. Where once I was 45 minutes aerobic (cardio and resistance). Pre Mayo I was told by local neurologist "keep exercising, it'll make you feel better", wrong!!! One of my primary symptoms was Exercise Intolerance. The 45 minutes would destroy me and I would need to lay down for hours to recover. Same with chores around the house with Post Exertion Malaise (PEM). I don't experience that anymore with my reduced level (and all the other elements of my Mayo plan). One of the best analogies I was introduced to my Mayo was that you must treat yourself like an injured athlete. You can't just back out there at the same level, you need to work up to it. Hopefully you can start super simple and ultimately work your way back.
