I Had a EMG Done for Nerve Damage on my Left Side Flanks Due to Smart Lipo. Why Was the Test Done on my Thigh to my Feet?

No more then 3 weeks later after my surgery on my flanks I have bee in constant pain. I have a tingling feeling and a ache in my left flake. They did the nerve conductive test on my and they say the machine showed no sign of nerve damage. I also had a MRI done on my back and showed no pinced nerves. I don't get it, the tingling feeling has not gone away in over a year since the surgery. This women doctor has does something wrong to me. I am 5"3 weigh 132 pounds. Help!!! What else could it be?
