Hello, I have studied your case, Due to blunt injury there can be hematoma collection .The bleeding that occurs result in hematoma collection. Over a period of time, as hematoma resolves it cause local skin symptoms around the hematoma. Continue ice application, and thrombhophobe ointment may help and take rest. You can do x ray to see for fracture, giving supportive splint will give early recovery. If required you may need to do blood investigation for prognosis and recovery. Take precaution to avoid infection around hematoma. Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us.
