In short

Dystonia is a movement disorder characterized by involuntary muscle contractions that cause twisting and repetitive movements, which can sometimes be painful. The condition can affect a single muscle, a group of muscles, or all muscles, with symptoms such as tremors, voice problems, or a dragging foot often starting in childhood, the late teens, or early adulthood. While some cases are mild, others worsen over time, and the disorder can be inherited or caused by another disease. There is no cure, but treatments such as medicines, Botox injections, surgery, and physical therapy are used to reduce or eliminate muscle spasms and pain.

Description

Dystonia is a movement disorder that causes involuntary contractions of your muscles. These contractions result in twisting and repetitive movements. Sometimes they are painful.
Dystonia can affect just one muscle, a group of muscles or all of your muscles. Symptoms can include tremors, voice problems or a dragging foot. Symptoms often start in childhood. They can also start in the late teens or early adulthood. Some cases worsen over time. Others are mild.
Some people inherit dystonia. Others have it because of another disease. Researchers think that dystonia may be due to a problem in the part of the brain that handles messages about muscle contractions. There is no cure. Doctors use medicines, Botox injections, surgery, physical therapy, and other treatments to reduce or eliminate muscle spasms and pain.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.

Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.

What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.

Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.

In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
