It's pretty routine to incorporate some degree of stretching as part of the patient's treatment plan, including in the cervical spine. Some stretches are pretty easy to remember and pretty straightforward for patients to remember when they get home. However 1 of the stretches that I find patients doing incorrectly high percentage of the time pertains to the scalene's. Doing it correctly is pretty important because failing to do so means you spending a lot of time with no return on investment, at best, and at worst, you can actually make your particular problem worse.

The scalene muscle group is located interior and slightly lateral to the cervical spine, and part of it attaches to the 1st rib. Both of these anatomical location distinctions requires some special positioning, set up, and order in which you incorporate the different directions of the stretch. Scalene muscular dysfunction is often associated not only with anterior cervical discomfort, but overload pain along the left scapula, as well as vague symptoms radiating into the upper arm, since the brachial plexus has to exit through the scalene's. If you're not setting up the stretch correctly you just don't get the results which is frustrating to the patient investing time in stretching.
