The hard thing about figuring out what movements cause is pain is the need to stop doing EVERYTHING, get things calmed down and then slowly add activity back in one at a time. You have to be very methodical if there are a lot of possibilities. It also helps to add time increase in slowly. SOrt of like an elimination diet but for doing things.

This is how I figured out my saphenous neuritis which I feared was spread. I stopped everything and started up again about two weeks later. Turns out I was aggravating that nerve on the recumbent bike. My doctors couldn't figure out why my whole leg was buzzing. It was fluke that I figured it out because I had an injection in my foot and thought I should lay off everything and voila, the buzzing pain stopped. It had been going on for a year!
