I took a fall on thanksgiving. I am a 46 yo female with previous back surgery and degenerative joint disease. Lumbar injections done in sept. Since the fall, my hips and legs are very stiff and sore. I walk funny and I've had several headaches. Is this to be expected or might there be something more serious going on? I fell from one step when the ramp that was usually there was moved and I wasn't aware. This happened at home.
