hello.there is a chance of local infection and inflammation of the area is what is causing you the pain.do not wear any jewellery there till it subsides, you might claen the whole of the area with hot water,dry it completely with a clean or sterile swab and apply any antiseptic you have at home.
if the pain and swelling is unbearable get an opinion of the ENT OR general surgeon
. you might require appropriate analgesics and antibiotics depending on your symptoms and signs.
hope i have done the needful.
