As a Neurologist
, the one question in your statement, which I can answer, is the numbness
you feel in right upper thigh. It is called Meralgia Paresthetica. Not to worry about it. It's caused because a superficial nerve in your skin gets affected-- usually by sudden weight gain or loss, as in pregnancy, and sometimes by clothing which is tightly fitted at the waist. Usually heals by itself over weeks and months-- don't wear tight clothing at the waist. Medications maybe used of the symptoms are bothersome.
