This is silver's hubby again:
I'm may not be a doctor, but I stayed at a Holiday Inn Express last night...
I believe that you can check for a serious misalignment by standing on two identical scales at the same time (maybe at Bed Bath and Beyond).
Theoretically, a balanced body will weigh the same on both scales; the more difference between the two scales, the greater the misalignment.
Might be an easy self check without spending money
