Hi and welcome to HCM
It might be soft tissue injury
with or without nerve injury
Without X-ray, it is difficult to differentiate a fracture from others. I suggest you to consult an orthopaedician nearby for a detailed examination. You may get the X-ray/MRI of the area affected under his/her guidance.
Meanwhile you can take anti-inflammatory drug like motrin
to reduce pain and inflammation. Avoid lifting weight and rest well.
I do hope that you have found something helpful and informative and I will be glad to answer any further query.
