For the past week, I have had excruciating pain in the center of my
knee that radiates to the outside of my thigh. This
pain is on the left side of my body. I have noticed some puffiness around the knee and below it. There is no warmth in the knee or on my thigh. I've popped OTC painkillers like Advil and Aleve to no avail. I can't tolerate any pressure on that side, including when lying down. When sleeping, I have to straighten my left leg out flat.
