Hi I fell and jammed my knee, the next day my back has been hurting on lower right side, 2 months now , it especially hurts when laying down or sitting, sometimes walking too, i have had to actually had to climb up my leg to get up, its very sore alot and feels stiff and tired, i had femur fracture almost 2 years ago and have rod, could i have mis aligned my rod and could it be hitting a nerve,? the pain travels down my leg at times and over to buttocks and hip area
