Had an odd thing happen to me after a colonoscopy a couple of months ago. I was lucky to get an appointment as soon as I did. Someone canceled and I was able to squeak in there. They gave me the propofol-fentanyl cocktail as they were wheeling me in to the surgical area. I was out soon after. I woke up during the procedure and started talking to the doctor and the techs.
"So, where are we now?"
" We're just about to knock out a polyp. You had three of them. This is the last one."
"Great. How's it going?"
"Just fine. They all look benign. Can you see the monitor? Let me turn it towards you. Here's the polyp. In front of it is a diverticulum. I'm gonna get the little lasso around it.....there. Done. We're just gonna take some pics on the way out."
There was a guy in the room who had 12 feet of wire spooled out in my ass but I didn't even give it a second thought. I must've conked out again because a nurse was waking me up in recovery.
My wife took me home and I had some food. Spent most of the day recovering, eating, and hydrating. Felt a little chilly which I attributed to the lack of calories. Went to bed wrapped up in my bathrobe.
After 90 minutes I woke up and was freezing cold. My teeth were chattering hard. At first I thought it might be a calorie deficit but got up and took my temperature. It was 103.4 degrees F. Took two Tylenol and got into a sleeping bag. My teeth chattered so hard, I was afraid I would break the thermometer. About 45 minutes later, I checked my temp again and it was 103.8 F. It's still going up. We had a rapid COVID test and I burned it. Luckily I was negative.
Then I peed and it felt weird so I thought I had a UTI. We had some cranberry extract so I drank some.
My temp started coming down about an hour later. At 8:00 am, I called the doc at the colonoscopy center and told him my symptoms. He told me this:
"Look at it this way. You starved your body for 36 hours, eating only lemon jell-o and drinking Gatorade. Then you swallowed the equivalent of 18 doses of laxative and pounded a couple gallons of water. After that, we loaded you up with hard drugs which could easily feel strange when peeing them out. You're also running a huge sleep deficit because you didn't get any the night before and it certainly sounds like you didn't get any last night either. Adverse reactions to the procedure are rare but certainly not unknown."
I was back to normal temp by 2:00 pm and felt almost human by suppertime.
This stuff happens but it needs to be done. I have to go back in three years.
