Never stay in a jacuzzi longer than 10mins!! my boyfriend fainted horribly after we got out, hit his head and cut the bone under his eyebrow, had a siezure as a result of the fall...and was  pulling in and out of consciousness. It was very scary. Never enter a jacuzzi on an empty stomach either because your sugar levels drop and you become more likely to have the same experience. I would like to ask though if he would need an xray in case? we went to the doctors and he got his skin glued together but they never gave him a referral to get a brain scan...please help as i'm a worried girlfriend.
