What Causes Popping Sensation In My Right Knee And What Is The Treatment For Bruising Near The Knee Cap?

Question : I am on my second round of cortisone shots in my knees due to arthritis. I fell hard on my right knee and slightly on my left on concrete one week ago. I am 200 lbs.. I am able to walk and have no pain but do have some stiffness and slight swelling. Pain is only when you push hard on it feeling like chards of glass cutting me. Bruising however is on the right inside of my knee cap area an, underneath the outside of my right knee under my knee cap..then on the outside of my right calf and slight bruising that extends almost from my ankle to my knee dead center down the middle. The bruising has not gone away too much. The center of my knee cap on the right there seems to be a slight dent. Again no pain. I have felt a ripping sensation and my knee is numb from knee cap to half way down shin that i could feel in the beginning when you scratch or rubb that area in my toes with a tingle. I told my husband that I dont want anyone to fix it because it is the first time in a long time that I have no pain in my knees. I am 50 years old and a woman. He is pushing for me to go to the hospital I think it is a waste of time. My left knee is popping. I do not know if my knee gave out or popped but most definitely heard it crush/crack/grind. I know this sounds bad....but again, I have no pain and it is a welcome relief i treat almost daily with two tylenol and motrin 800 mg. right now I am taking 1 motrin but lower dosage to keep swelling down which there is little of....mainly where the most severe bruise is on the inside of the right knee bone.

You have not addressed the numbness. Is there an explanation to this and why it would extend halfway down my leg. I understand that the xray will determine more then trying to answer something via message.
