i am not a doctor but i would think that you would have a slight limp if
that much shorter and also it may cause some joint problems ets. now a
problem in the spinal chord could cause some nausea etc but i just dont
think it is related to the leg being shorter myself. but i would
go to another doctor and see what he says to be sure. even another
chipopractor and not say that you had been to one . second opinions
are always best.
