Trauma to the ear can be painful. I would like to know whether this was a sharp , or a blunt object which hit you . Assuming this was blunt trauma
, swelling would be there , and pain over the Pinna will persist for a few days at least. you need to start taking a painkiller , and a serratiopeptidase
( to bring down the swelling ) . If it is a mild trauma , the pain should settle in a few days
If the swelling is increasing , or part of your ear is feeling boggy -- it may indicate a collection of blood ( a hematoma
) , and should not be ignored -- you should visit a local ENT doctor.
Feel free to get in touch if you have any further queries
