All a bit clearer now.
Op will only take approx. 45 mins - so I won't be bothered if I have to take it off for let's say an hour or so. It can be getting on for that sometimes when I have a shower, hairwash etc and don't pass where I left it this time while I'm drying, cutting toenails, whatever.
I was all over the hospital today! I thought it would be quite relaxing as the Day surgery unit is through the main entrance, and turn immediately right. Well the bit that was in there was fine. But then I had to go and have an ECG and a breathing' test so that was at the completely furthest part of the hospital, plus on the first floor. Didn't have to wait all that long TBH and the ECG seemed OK, but the breathing thing wasn't. They stick a nose clip on you and you have to breath through your mouth, but they don't allow for a person with (sorry, bit revolting) post nasal drip. Of course I have nose drops and an inhaler and when I know I have to have a breathing test I use them for a few days beforehand but not all the time because the nose thing tells you it causes thinning of the skin so you can't use it long term - and the inhaler is steroids hence I only use it when I really need to. I didn't know I had to have this test else I'd have prepared for it. I'd already decided to use them from the weekend immediately before the op, anyway. Sooo - I hope that result will be OK ….
Also had to go for a blood test, which I expected and it's on the ground floor more or less directly underneath the Cardio Respiratory place, so that's fine. However - amongst all the 'usual' when we're us, they're doing TSH as entirely expected PLUS T3. Haven't had that done by my GP or the hospital I see for my diabetes where all the initial input into my thyroid was instigated - for years and years and years so it will be interesting, anyway!
