What does Clonus feel like?
Clonus is experienced as rapid, rhythmic muscle contractions followed by brief relaxation — most commonly in the ankle, wrist, or knee. It may feel like a repeating twitch or tremor that you cannot control, often described as a series of quick jerks. Some people notice clonus as a fluttering or rolling movement under the skin, while others feel the limb being pulled into repeated involuntary motions. Episodes may last a few beats or continue in short bursts, and they can be triggered or worsened by stretching the affected muscle or changing posture. Emotionally, clonus can be alarming because the movements are involuntary and unpredictable.
Common Causes
- Upper Motor Neuron Lesions – Damage to the brain or spinal cord pathways that control movement.
- Multiple Sclerosis – Demyelinating disease affecting nerve conduction.
- Stroke – Acute brain injury leading to motor pathway dysfunction.
- Spinal Cord Injury – Trauma that disrupts descending nerve control.
- Certain Medications or Toxins – Drugs that alter neuronal excitability.
Red Flags: When to see a doctor immediately
Seek urgent medical evaluation if clonus begins suddenly, is accompanied by weakness, loss of coordination, difficulty speaking, numbness, severe headache, or visual changes. New clonus after trauma, sudden stroke-like symptoms, fever with neurological changes, or worsening frequency that interferes with breathing or swallowing require immediate attention.
Home Remedies & Immediate Relief
There are no true “home cures” for clonus, but short-term comfort measures can help: gently supporting the affected limb, avoiding positions that provoke repeated stretching, and using relaxation and breathing techniques to reduce muscle tension. Maintaining hydration and correcting electrolyte imbalances if present may decrease excitability. These measures are supportive; definitive evaluation by a neurologist is often necessary to identify and treat the underlying cause.

Frequently Asked Questions about Clonus
Is clonus the same as a tremor?
No. Clonus is rhythmic, often stimulus-triggered contractions linked to neurological injury; tremor is usually different in cause and pattern.
Can clonus go away?
It may improve with treatment of the underlying condition or targeted therapies.
Does clonus mean I have MS?
Not necessarily—clonus has multiple causes and requires evaluation to determine the reason.
Are medications available for clonus?
Yes, neurologists may use muscle relaxants or other agents depending on cause and severity.
Should I avoid exercise with clonus?
Light, supervised activity is usually beneficial; avoid movements that provoke severe spasms until evaluated.
