I usually get my pinched nerve on my left leg and lately i have been feeling in on my other leg (knees down)? could this be my pinchenerve?

Different nerve: If you are having problems in the other leg, it would have to be a different "pinched" nerve. However, some rather large, central disc herniations or bilateral narrowing can cause problems on both sides.

EVAL- DIAGNOSE TREAT: Exam and eval is essential for radiculopathy or disc problems metabolic can do similar symptoms MRI and EMG study needed . Trial therapy can help in diagnosis rehab/pain/ortho can help.

Leg pain.: It is strongly recommended for you to obtain a MRI lumbar spine to rule out any disc herniation or spinal cord/nerve root compromise.
