When the disorder occurs in people with a family history, it is referred to as spasmodic torticollis. Bending or twisting your neck too far can lead to acute torticollis. Few symptoms are associated with this condition; you will experience discomfort and will hold your head straight or rotated to one side. Moving your head to the opposite side will usually precipitate pain. The neck muscles on the affected side often are tender to the touch and tense. Acute torticollis will make you unwilling to turn your head to one side, or forces you to turn your head slightly away from the side of discomfort.
Other symptoms may include shoulder pain, back pain, headache, neck cramps, muscle tightness, or burning sensations
In adults, acute torticollis can be the result of many different conditions; occasionally, no condition is found as a cause. Trauma to the neck or spine, as in an inappropriate sleeping position, can lead to torticollis. Injuries to the cervical spine or neck muscles often cause spasm of the muscles, leading to the twisting of the head, characteristic of torticollis.
Other causes include infection of the head or neck. These infections can cause an inflammatory torticollis secondary to inflamed glands and lymph nodes in the neck. The muscles that are on top or adjacent to these lymph nodes contract. Torticollis may be associated with abscesses of the throat and upper airway, and those situations can be life-threatening. Other infections of the sinuses, ears, mastoids, jaw, teeth, or scalp can lead to torticollis.
The aim of treatment for torticollis is to relax the contracted neck muscles involved. Treatments include medication (non-steroidal anti-inflammatory drugs, muscle relaxants), physical devices, botulinum toxin, physical therapy, stretching exercises, and ultimately and in severe cases, surgery. In most people, torticollis resolves in a matter of several days to a few weeks.
It is a matter of time till you figure out if your torticollis has resolved (if no pain recurs in the next few hours) or if this is just the effect of Valium.
