I know there are different causes and different ways for getting blocked but just as an anectode, every cat I know who got blocked, two of which are in the family, got blocked after a stress. The ones in the family, after moving homes.
Some got better after just one blockage or two but for some others it takes time. Cousin's cat for example got blocked twice in 5 days. There are different treatments (including food) to try. If one clinic seems to not help, personally I would definitely try another clinic before considering putting to sleep. And re-check diet and water intake.
