Mr Singh will strap you up and he says you need to leave the strapping on for a minimum of 4 days buts preferably until your first week check with the nurse. I’m wearing my Macom aswell ( I’m 6 days post op and the nurse is taking the stealing off today ) and when I spoke to the nurse from MYA after my op as they call you the next day she said it will do no harm at all wearing both and will offer extra support but it’s all down to the individual and what they are comfatable in as some people find the tape really tight and some don’t.
I would take your Macom to the hospital with you and then you can decide after your op whether you are ok to with or without it x
