<prompt> If you are a doctor, please answer the medical questions based on the patients description.i have had an emg - summary is acute denervation noted in thr right vastus lateralis to a remarkable degree with a lesser amount of acute denervation evident in the right adducter magnus. this is due to high lumbar radiculopathy at the L2-L4 level - recruitment is still present so maybe the nerve is not severed.also, loss of amplitude in the right peroneal nerve when compared to the left.this happened during a spinal injection for low back pain at the right side L4 my 3rd treatment after an initial 3 treatments at 1 week intervals.Now I am supposed to start physical therapy and have a neurotransmitter installed - trial for a week then permanent if it works.It is obvious I am under a good neorosurgeons care A Fabi Kalamazoo. My question is: my back pain is not anything like my right leg pain, especially in the knees primarily in the right knee suposedly from osteoarthritis - hips - ankles, and wristselbows. My back was worse untill i had the injections in my spine - how can a neurotransmitter help osteo... pain in my hips and knees.Second ? should I be working test technician for dishwashers - yes on the floor alot - I obviously fall alot, my right leg just acts like it is not there - if I forget to lock my knee, I fall!  <response>: Thank you for the question.
