<s>[INST] I woke up with leg pain a couple days ago on the one side of my leg. The pain started on the right side of my lower pelvis, and progressed to my back. Now both of my legs are in severe pain to the point I can not move them. What is this? My doctor is clueless and is calling me a mystery..  Help? [/INST] Hi there. This sort of pain could be due to either :1. Pelvic inflammatory disease.2. Lumbar canal stenosis. This is more likely. Kindly get an ultrasound of the abdomen along with X-ray of the lumbosacral spine. Get them evaluated by an expert. Kindly start on antibiotics and painkillers according to your GP's prescription. Add a muscle relaxant to the combination. I hope my advice has helped Good luck </s>
