Brief answer....nothing to worry 
Detailed answer....
Hello,
Thanks for the query.
I have read your query and understand your concern. Although unusual but vessels can break during rough sex. Such type of vessel injury heals itself provided it is given time and not traumatised by further use. 
This bruise would go away in around two weeks time.
Since you don't have any pain now,it seems everything has settled.
As far as numbness is concerned,this is also temporary and would be all right in next few days.
Nothing is to be done now. Just wait and watch for it to heal.
No medicine is needed.
Watch out for swelling and pain. If it re occurs,then you would need to consult your doctor.
I hope it helps,however you are most welcome to revert to me for any further query.
Best of luck
Thanks
