Hello. Thanks for posting your query. From description it seems to be soft tissue injury or ligament injury. You need an x-ray to rule out any bony injury. I suggest you to consult an orthopaedician nearby for a detailed examination. You may get the X-ray of the area affected under his/her guidance. Beside icing and elevating it, you can take anti-inflammatory drug like motrin to reduce pain and inflammation. Avoid putting weight and rest well. Wishing you good health Regards. Dr Saurabh Gupta
