Torticollis, also known as wry neck, is a dystonic condition defined by an abnormal, asymmetrical head or neck position, which may be due to a variety of causes. The term torticollis is derived from the Latin words tortus for twisted and collum for neck.The most common case has no obvious cause, and the pain and difficulty with turning the head usually goes away after a few days, even without treatment in adults. Signs and symptoms
Torticollis is a fixed or dynamic tilt, rotation, with flexion or extension of the head and/or neck. The type of torticollis can be described depending on the positions of the head and neck. laterocollis: the head is tipped toward the shoulder
rotational torticollis: the head rotates along the longitudinal  axis
anterocollis: forward flexion of the head and neck
retrocollis: hyperextension of head and neck backwardA combination of these movements may often be observed. Torticollis can be a disorder in itself as well as a symptom in other conditions. Other symptoms include:
Neck pain
Occasional formation of a mass
Thickened or tight sternocleidomastoid muscle
Tenderness on the cervical spine
Tremor in head
Unequal shoulder heights
Decreased neck movement

Causes
A multitude of conditions may lead to the development of torticollis including: muscular fibrosis, congenital spine abnormalities, or toxic or traumatic brain injury. A rough categorization discerns between congenital torticollis and acquired torticollis.Other categories include:
Osseous
Traumatic
CNS/PNS
Ocular
Non-muscular soft tissue
Spasmodic
Drug induced
Oral ties (lip and tongue ties)

Congenital muscular torticollis
The congenital muscular torticollis is the most common torticollis which is present at birth. The cause of congenital muscular torticollis is unclear.
Campylobacteriosis is an infection by the Campylobacter bacterium, most commonly C. jejuni. It is among the most common bacterial infections of humans, often a foodborne illness. It produces an inflammatory, sometimes bloody, diarrhea or dysentery syndrome, mostly including cramps, fever and pain. Symptoms and signs
The prodromal symptoms are fever, headache, and myalgia, which can be severe, lasting as long as 24 hours. After 1–5 days, typically, these are followed by diarrhea (as many as 10 watery, frequently bloody, bowel movements per day) or dysentery, cramps, abdominal pain, and fever as high as 40 °C (104 °F). In most people, the illness lasts for 2–10 days. It is classified as invasive/inflammatory diarrhea, also described as bloody diarrhea or dysentery.There are other diseases showing similar symptoms. For instance, abdominal pain and tenderness may be very localized, mimicking acute appendicitis. Furthermore, Helicobacter pylori is closely related to Campylobacter and causes peptic ulcer disease. Complications
Complications include toxic megacolon, dehydration and sepsis. Such complications generally occur in young children (< 1 year of age) and immunocompromised people. A chronic course of the disease is possible; this disease process is likely to develop without a distinct acute phase. Chronic campylobacteriosis features a long period of sub-febrile temperature and asthenia; eye damage, arthritis, endocarditis may develop if infection is untreated.
