Thanks for your query.
It seems from the description that you could have suffered a soft tissue contusion
with resultant muscle spasm causing you symptoms
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.
I do hope that you have found something helpful and I will be glad to answer any further query.
