I'm having left leg outer thigh numbness,its been coming on for a year .then it started like pins poking pain and burning. I had a EMG at neroligist. Its called MERALGIA PARESTHETICA. Google it. It's a pinched or trapped nerve. Femerol nerve. The nerve that let's you feel on the side of thigh. Its caused from tight clothing, or belt .Also from weight gain. It usually is only on one leg. My dr said after I loose weight it will start to heal. It itches also. And I get burning pain. The pain came on after 6 months of numbness. My surgery gastrectomy was March 4th. I'm down 13 lbs. Started at 210 now 197 5ft and 1/2 inch. I hope this pain stops soon. I'm on gabapentin and norco pain meds it hurts bad. Google it.
