I had a cyst removed from my thyroid gland. It had been there for years, visible, but completely harmless. Until it got infected, then it swelled up to the point that it took up about 30% of the circumference of my neck.
The infection was treated and the cyst went back to its normal size, but I had surgery a few months later.
When I woke up from the anaesthetic I had three unpleasant surprises; one, I started to choke due to build-up mucus in my throat. I kept sitting straight up like Frankstein's monsters in an old film but a nurse would just slam me back into the bed. Second, there was... something hanging out my neck. I just assumed the stitches had burst and neck meat or whatever was spilling out. My mom had to explain to me that I had a small bottle attached via a tube that went into my neck to allow fluids to drain. Thanks to doctors for not filling me in on that one. Lastly, someone had taken off my underwear for some reason. I had worn them because this was the NHS in the mid-90s and making a 16-year-old boy walk to surgery with his arse on show for all to see was acceptable. I disagreed, hence the Y fronts. Why the fuck take them off in the middle of surgery though? Was Jimmy Savile visiting that day or something?
