I also started with it in my left foot, & almost immediately after strange sensations started in it, same thing in the right. 2.5 yrs more or less later started in with my left hand, then immediately in my right hand. GO FIGURE?? I sure can't figure it out *LOL*. I have a less muscular left leg cause of compensating for the one that hurts the most, the left foot. I did have SGB's right away for the hands & they really helped. I don't think the left arm/hand is less in size than the right one. The LSB's for feet happened almost a year from first onset of symptoms. Not as effective. I am having lots of symptoms in my hands again, they are happening alot more aggressively this time. Starting SGB's Jan 2nd. They do a series of 6 per side.
