I started on the treadmill holding the sides, eventually I started biking and walking outside in addition to weight resistance training. After years I found that my coordination and balance have improved to near normal. ( no affect on the tightness or night pains) . This is at a level of averaging 9 miles and over 20k steps per day. The minute I take any time away from this routine , bam I go right back to where I was with bad coordination. No supplements or gabbapentin do anything for me. I have not focused on diet, but I mostly avoid junk and fast food. But nothing I have tried has completely masked the symptoms.
