I have taken a fall 9 days ago and injured my ankle, at what i thought was just a sprain. However now i am able to bear weight and walk wihtout a limp, yet htere is still some swelling, but sever point tenderness along my lateral malleolus, at the bottom, and on the posterior edge, along with a very achy and sore feeling. it also feels quite stiff when I plantar and dorsi flex. Should I get an xray done?
