Understand. I was a walker and bike rider until I was 64. Then I began to feel bad, ear and sinus issues for which I had surgery last July. Then lung issues and next kidney issues kicked in. Finally diagnosed with ANCA GPA Vasculitis in November, then had a major flare with ICU stay. Not sure I will ever be "me" again, but very thankful I have finally begun to regain some strength. Praying for your renewed strength. Blessings.
