Thanks for posting your query.
From description it seems to be soft tissue 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.
In the interim, you can take anti-inflammatory drug like motrin
to reduce pain and inflammation. Avoid putting weight and rest well.
