The only “most helpful” procedure I have found is PRP. Some orthopedics do it, but I went to a Musculoskeletal Doc who specializes in Stem Cell, PRP, Prolotherapy and Manipulation. Unfortunately, with age and the body’s natural decline, my personal experiences have been bleak. A healthy diet without dairy and most grains helps as well, but age is only a friend to wisdom and knowledge, in my experience. SUGAR is your worst enemy. Try to eat Organic. Autoimmune issues SUCK! There can be moments or brief spans of remission, but there is always a relapse. It seems that there is always a monster ready to jump out of the next door. Cherish the moments you get and as much as it hurts you, maybe pick up another hobby to fill the gaps. Try to find joy in the moments you get and be patient with yourself. At 52, my monsters are real jerks, but seeking ways to serve helps me. Seeing others happy, makes me happy. I wish there was a miracle repair, so many advertisements imply it’s possible, and good for those that do…but reality is the majority don’t. Cherish the memories and find ways to make new ones. Focus on what you CAN do. Blessings and good luck in your journey.
