@Thewildthingsarewithme, you come far, far down on the list of embarrassing moments, let me assure you!
Some of mine are:
After giving birth to second Dc after having an episiotomy with the first (I tore with DC2).
Midwife: 'I'm going to get someone else in who is better at stitching than me as you're torn along your scar'
Me: 'ok'
Midwife: 'Do your mind if X comes in to watch'
Me: 'help yourself - everyone's seen it anyway!'
DC1 to me after having extensive prolapse repairs (many years after the above) and repeated antibiotics due to a nasty infection: 'blimey Mum, isn't there anyone who hasn't seen your fanny?'
Me: wry smile 
Me nearly sg myself after unsuccessful bowel prep prior to an endoscopy:
'I need the toilet'
Cue a scramble to get me as fast as possible to the nearest toilet and get my sandals on my feet - I made it (just) but became very aware that the entire recovery ward could hear everything. 
I could go on, but will mention one last event closely related to yours:
I'd experienced palpitations over five days and was very worried, so I took myself to A&E. Due to the problem (the nurse could hear that my heart was beating erratically), they told me I should be in Majors, but there wasn't space so they would take me to Minors.
When a bed was free in Majors, they moved me, but wouldn't let me walk, so I had to go in a wheelchair. Once I got there, I realised my entire right arse cheek was on show
. The only saving grace was that I never saw any of them again.
You are not alone!
