This thread was really helpful to me before surgery, so here's my contribution nearly 6 weeks after my surgery.
1) Unlike some of the others, I had practically no pain. I mean, trying to cough, trying to lift things or do anything beyond my capabilities hurt, but when I wasn't doing those things I really didn't experience any pain.
2) Having said that... I deliberately haven't sneezed in 6 weeks, so maybe that's why I haven't had pain! The holding-nose move works well, and I've taken antihistamines daily.
3) I don't know if it was the surgery or the general anesthesia, but the impact on my brain was noticeable. I'm a migraine sufferer normally with only one migraine every 3-4 months. But I had between 10-20 migraines in the first 48 hours following surgery, and they came pretty frequently for about 3 weeks until trailing off. I haven't had one for a couple weeks now.
4) My first day in the ICU all I wanted to do was sleep. But I would nap for only about 15-30 minutes at a time. At least... that's what I thought. Once I could see the clock, I realized that these 15 minute cat naps were REALLY only about 1-2 minutes long!!! My entire sense of time was screwed up. Not sure if that was the medication or the after-effects of anesthesia. It's wild to think about, but I have to admit it was not pleasant the way time was dragging like that when all I wanted to do was sleep.
5) I also had some memory loss and confusion early on. I don't remember a lot of my hospital stay. When I first arrived home, I slept for about 15 minutes and woke up not really knowing where I was or why there was a scar on my chest! Things got a lot better after the first night home, but the first night home was a little scary actually.
6) One morning in the hospital I woke up with the oxygen tube from my nose touching my mouth and the taste was terrible. I've had that taste every so often ever since leaving the hospital. So weird!
7) Sleeping in the recliner for a couple weeks wasn't so bad. I actually slept really well.
8) Cleveland Clinic was good, the nursing staff was great, but for such a large hospital that allegedly does more of these than anyone, I was surprised that they didn't have enough stepdown beds. As a result, I spent nearly 4 days in the ICU!
9) Dr. Svensson came to my room in the ICU and said my valve was so calcified (he said "like sandpaper") that he said he often sees patients like that present with stroke. I'm still surprised he used the word "often". I guess I was lucky I didn't wait any longer.
10) I had two head CT scans in the hospital because in my 1st night I experienced transient left eye vision loss. Their thought is that I had a very tiny clot kicking around my system that may have caused a brief occlusion of the retinal artery. It only lasted 5 minutes or so, I think. And no problems since.
