I fractured my knee over the summer. A couple of wks ago I was walking my dog, he pulled me I fell with all my weight on that knee. Since then I have severe pain when I walk, swelling. Ibuprofen and tylenol, bracing does not help. Dr. says it’s not broke she thinks I bruised a bone. What do you think?P.S. She only x-rayed it never did a MRI, she told me to go to physical therapy for 3 wks. and if its not better to let her know.
