Long-term back pain that counted as a pre-existing condition for every insurance package I had, on the rare occasions when I could afford to be insured. That eventually degenerated into a couple of prolapsed disc that cut off the nerves to may legs, resulting in constant pain (the kind that leaves you screaming and writhing without a constant morphine drip) and making it impossible to walk, sit up, or go to the bathroom unaided. While not technically a life-threatening condition, my quality of life was low enough that I certainly would have committed suicide had it persisted indefinitely. In the US, as I say, this would not have been covered by my insurance, and would have cost around $50,000 to fix. Completely infeasible for me to find that amount of money. The NHS did an excellent job of fixing it for free.
