Glans still hurts after a week from teethy blowjob

I received a blow job a week ago and a spot on my penis tip still hurts after a week. It doesn't look bruised or red so I'm thinking it's hypersensitivity from a struck nerve when i was thrusting? He also might have sucked it really hard. There's a dull pain when touched or rubs on clothing. Anyone else had similar issue? How long did it take to heal? My underwear keeps rubbing the sensitive area throughout the day which may keep it from healing faster so im trying to prevent friction.
