I had my knee hit during work ank swelling started, x ray shows no sign of fracture.?

Doctor say it should be a fluid problem. I have severe pain while walking and bending. what is the best treatment

See a professional doctor such a bone and joint doctor who is a specialist in the field. I had to end up having knee surgery b/c of my knee problem. Trust me seeing a specialist instead of a regular doctor is better. My "regular doctor" (whom I know longer see now) screw me over and misdiagnosed me! Try propping it up with an ice pack with a pillow under you knee and contact a specialist.
