Actress Nikki Tamboli, who was a finalist in 'Bigg Boss 14', recently underwent an eye surgery for a medical condition called chalazion. Chalazion, often mistaken for an eye stye, refers to a bump on eyelid formed due to oil accumulation in the glands. "It usually...dissolves with heating pads. However, in my case, it didn't," said Nikki while sharing a picture.
