I had my pre op on Monday, the nurse runs through everything in more details hospital details things to do before & after op what expect etc, weighs you, measures your height, takes blood pressure & swabs for MRSA, runs through sheet on health , take a before pic, and books your week check up when have strapping off. You don’t get to try sizes on again but can make another appointment with surgeon. I’m seeing my surgeon on 27th nov so I’m 100% sure on size decision. X
