Diddy hosted a post-Grammy party at the Playboy Mansion Sunday night .After the party, Diddy went home and got a massive headache.
Diddy's entourage became so concerned ... they drove him to the emergency room ....
Diddy was treated and is back at home ... feeling a lot better. A Diddy source tells us ... the migraine was unrelated to anything that went down at the Mansion. Peep a photo of him at the party via TMZ below
