What was medicine like in the old west (1840's - 1890's)? How educated was the average doctor? What equipment and medicine did they have at their disposal? Did most small towns have local doctors? If so, did the doctors do house calls, or did they actually have a kind of clinic in the town? How much did they charge for their services, or did that vary too much to answer?
Changing rapidly, but reasonably similar to what it was like in the United States (proper, not territorial) at the time. Small towns would have had doctors based on population (so a town of 50- much less likely than a city of 5000), and much like other Victorian doctors they would have usually done both house calls and office visits based on the needs of patients - you might have gone in for a broken finger, but he may have come to you for a broken shin, depending on how far away you were.
