The Fashion Police host was injured last week when she tripped up on the set of America's Got Talent.
She tweeted: "Sorry to be a complainer but this sprained ankle is driving me nuts i cant do anything by myself! #CantStandPeopleHelpingMeWithEverything
"I mean i even need help having a bath it makes me feel like a baby!"
Kelly went on to say that her choice of footwear is also limited for the time being.
She added: "I know this is the most superficial complaint yet but i cant wear heels! ;( I'm 5'2 on a good day ... ok i will shut up now!"
Because of her ankle injury, Kelly was not around for mum Sharon Osbourne's debut of her new jewellery range on the Home Shopping network on Sunday.
However, she was still able to lend her support by calling into the station and praising the accessories, which include bracelets and necklaces and details such as elaborate embellishments, angel wings, thick crusts of gemstones and crosses.
