I don’t believe my scoliosis has gotten noticeably worse. Maybe some since the 1950s but I have 20+ yrs of bone scans and my spine at least looks unchanged. 3% a year over some of that period should show some change. I exercise regularly and walk 2 to 3 miles a day depending on the season. I am even still skiing which makes my Dr cringe. Hope to maintain my lifestyle for a few more years which may be all I have left.
