I have tight scalenes and had them from typing and desk time before getting into lifting. Went part and parcel w/ somewhat knotty traps too. Chair massage (over weeks ) helped.
Versions of this stretch http://calliesmassageblog.blogspot.c...e-stretch.html done at a couple of angles of lean and rotation really hit some tight areas for me that released over time. This is what the massage therapist was doing among other things (it was participatory in that she would hold down on them and i'd pull on my head or vice versa). After i stopped going they slowly tightened up again. I can self administer it but i don't have the attention span since it doesn't cause me any active disfunction/pain that i'm aware of.
