Then don't do that!`

Alright, the joke is that the patient says "Doctor, it hurts when I do this" and the doctor says, "Well then, don't do that!" but the thing is people do stop doing things when they hurt, or to be specific, limit their range of motion rather than working out the painful area. This results in a cycle of pain increasing and range limitation.

Yes there are things like broken bones where it is good to limit motion for a time, but the thing is that there are many instances where this is not the case and the above scenario is happening.
