what meds are you on? usual cause of being sick is 1, codeine, it’s pretty strong stuff and it makes me sick, thankfully i knew this before my op and was prescribed something else, but it can make you quite ill as it’s strong. 2. it could be the anesthetic, have you had it before? if you drink plenty of water it usually pushes it out of your system quicker hun 🙂
i wasn’t strapped so can’t comment but it could just be the strapping having an air pocket of sorts xx
