In reply to The Lemming:
Sorry to hear that, and glad it turned out well in the end! Stuff like this* was one of the reasons we went back home, eventually, even though otherwise we loved our time in the UK. Felt a bit stupid to fly home every time you needed a quick dentist's appointment or, as happened to friends, did not want to wait a couple of months for the cancer treatment to start.

* For example, I cut my wrist badly doing some DIY work after buying the house we had initially rented, and covered the wound in tons of soot. Went to the hospital and was given a sterile drip to wash the wound while waiting in A+E, which would be fine. No stand for the drip, though, so I ended up balancing the wate bladder on my head, and no dish or bucket for the soot/blood/water mix to drip into, so I used a rubbish bin instead.
After a while a surgeon stitched me up without further cleaning out the wound, and I went home with some antibiotic.
Two days later a was a meeting at some other university, and woke up with my arm the size of my leg swollen with pus. So I pulled the stitches and opened wound again under the shower, squeezed out as much of the pus as I could, and went to see the campus doctor and nurse who were brilliant, cleaned the wound professionally and gave me the correct antibiotic. That was rather close to a sepsis and possible amputation, and could have been easily foreseen given the shit initial treatment.
