There is no such thing as writer's block. It was invented by someone in California who was too lazy to write.
Seriously, do CPA's get blocked? Plumbers? Do they call in sick because they simply cannot snake a pipe today?
Writers write. It's what we do. If you have run out of things to say on one subject, switch to another, but keep writing. Stephen King writes every day of the year except Christmas and his birthday and he's not doing to badly.

I find this kind of inane. It's comparing apples and oranges. Or more like comparing apples to broccoli. They are two completely different things. Writing is a creative activity. The others are basically rote physical activity with set problems and answers to those problems. If a writer is blocked, it could have any number of reasons. Maybe they're distracted by something, maybe there's a problem in the story that they're overlooking, maybe they don't have the plot worked out. I don't see at all how this comparison makes the least bit of sense.
Here's something else. I'm not Stephen King. What works for him does not work for me. I don't have to write every day to be a writer. I can write once a week and still be a writer. Might be a slow one, but I'm still a writer.
Everyone is different. You say go write something else. Well, that doesn't work for me. I need to stay focused on the task at hand and figure out the problem and if I go write other stuff instead, I'll never get anything done. I'd just end up with more random stuff that didn't go anywhere and all of which was probably not as good as what I could have had if I had only waited a few days because it takes me time to get into the mood and voice of a story. To imply that there is one single solution to the problem is as much of a fallacy as the plumber thing because it implies that everyone works the same way and has the same limitations and the same creative process. You might be lucky enough to never have this problem, but others do.
Personally, yes, I do on occasion get stuck on something. That's how I refer to it, btw. I occasionally get stuck, usually because something in the plot or tone of the piece isn't working, and I remain stuck until I can figure out something at least close enough to right to make out a first draft. It might be a couple of days, it might be a full week or two (and no, I don't tend to write during that period because it often just makes it worse for me).
My own personal tricks include working puzzles (lets my mind wander), listening to music that fits the character or the tone of the work, rereading the earlier parts to see if I've gone a wrong direction without noticing and to get my characters back in my mind, and sometimes working out a later scene first to give myself something else to think about, and usually in the process I can fill in the in-betweens.
