In December 2015, for some reason, my left leg wouldn't straighten out. So, when I walked, I often almost fell. As well, for the past 10 years, my lower back would hurt once every 2 or 3 months. I was unable to squat and sitting down or standing up was hard. I tried injections and massages, etc., but they didn't help. Not long after, even my right leg started to hurt. I knew that if it didn’t improve, I may need a wheelchair. That scared me. I used a cane when I went out, and my husband's left hand was my crutch.
