don't know if this will help. i had my first emg in 1992, along with my first lumbar spine mri. the mri showed i had a bulging disc and the emg confirmed radiculopathy. i don't remember when my last emg was. but i had an mri in may 2014, which showed 5 herniated discs, both foraminal and spinal stenosis, a grade one slippage of vertebrae, abnormallordatic curve, 2 torn discs and arthritis. i can braely walk from my living room to my bedroom without pain in my right lower extremity which shoots down my right leg. i start limping real bad and must sit for a few minutes before attempting to walk again.
