It absolutely makes sense that it feels best when you're resting it, BUT that is a short term strategy. The less you use it, the more atrophy you'll experience, and the worse your symptoms will become. The trick is to find the balance of using it without over doing it, and to build up as much endurance as possible. One of the "easiest" ways to rehab will be in a warm pool.

Blocks can be used for diagnostic purposes, but they can also help decrease pain for days or weeks at a time, so that you to rehab. There are other options as well, but they are not a bad way to start, IMO.
