When there was suspicion of back issues that could have cause my PN, I had an MRI a year ago. My back was found not to be in the best shape at all, but they still could not connect the PN with my back.

My back has been bothering me more then ever mostly on the lower left side. Lately I have also had horrible left hip pain which will also shoot down to my knee and then down the left leg. Sometimes it will run down the back of the leg, but mostly it follows down the side, hip, knee, leg. I want to say it feels more like a sciatica.

My question is, can something go wrong in the hip or pelvis that can cause sciatica or PN symptoms as well? Can something there become compressed? I have never had an MRI on those areas. Thanks...
