It always strikes me how often we hear that folks either won't go to the doctor to get something looked at, or they go to the doc and get the answer and then simply aren't compliant. If it's broken, fix it. I've never understood the logic behind avoiding the doc.
However, there is a different phenomenon. Sometimes, going to the doctor is not so straightforward. You have to go to a clinic, wait an unspecified amount of time to see the doctor. Once there, he'll prescribe several inconvenient things. And you know, we got stuff to do.
I went to a doctor a few months ago. I then had to do two tests, an abdominal ultrasound (which was fine, and I did), and several stool tests. These, I took my time. When I finally got around to doing them, I found out there is a time limit and the lab won't do them. I now have to go back to the doctor so that he can order them again. It's been months now.
I'll go back there... someday.
