I had to look up torticollis, do you think you have that Shell?

[Torticollis is one of a broader category of disorders that exhibit flexion, extension, or twisting of muscles of the neck beyond their normal position. In torticollis your neck tends to twist to one side. The condition can either develop slowly if you have a family history of the disorder, acutely from trauma, or as an adverse reaction to medications.

When the disorder occurs in people with a family history, it is referred to as spasmodic torticollis. The characteristic twisting of the neck is initially spasmodic and begins between ages 31-50 years. If you leave the condition untreated, it likely will become permanent.]
