Can't Stop Moving? Why Your Body Is Restless & Medically Approved Next Steps

If you feel like you can't stop moving, constantly shift in your seat, pace the floor, or feel an intense inner urge to move, you're not imagining it. Persistent restlessness is real, and in some cases, it may signal a medical condition that deserves attention.

One possible cause is akathisia, a movement disorder most commonly linked to certain medications. But it's not the only explanation. Understanding what's happening in your body is the first step toward relief.

Let's break it down clearly and calmly.

What Does "Restless" Really Mean?

Many people describe restlessness as:

• An intense inner agitation
• A strong urge to move constantly
• Inability to sit still
• Pacing, rocking, shifting weight repeatedly
• Feeling "crawling out of your skin"

This sensation can be physical, mental, or both. The key distinction is whether it's occasional (like after too much coffee) or persistent and disruptive.

What Is Akathisia?

Akathisia is a medically recognized movement disorder characterized by:

• A powerful inner restlessness
• A constant need to move
• Repetitive movements such as pacing, leg swinging, or shifting
• Significant discomfort when sitting still

Akathisia is most commonly caused by certain medications, particularly:

• Antipsychotic medications
• Some antidepressants
• Anti-nausea medications
• Certain mood stabilizers

It may develop:

• Shortly after starting a new medication
• After increasing a dose
• Sometimes even after decreasing or stopping a medication

Importantly, akathisia is not anxiety, although it can feel similar. It is a neurological reaction involving dopamine pathways in the brain.

Without proper treatment, akathisia can be extremely uncomfortable. Fortunately, it is treatable once identified.

Other Common Causes of Constant Movement

Akathisia is just one possible explanation. Other conditions can also make you feel unable to sit still.

1. Restless Leg Syndrome (RLS)

Restless Leg Syndrome causes:

• An overwhelming urge to move the legs
• Symptoms worse at night
• Relief with movement
• Tingling, pulling, or crawling sensations

RLS is often confused with akathisia, but it typically affects the legs more than the whole body and is worse during rest or sleep.

If you're experiencing leg discomfort and an uncontrollable urge to move, especially during the evening or when trying to rest, you can check your symptoms using a free Restless Leg Syndrome symptom checker to help determine if this condition matches what you're feeling.

2. Anxiety or Panic Disorders

Anxiety can create:

• Physical restlessness
• Fidgeting
• Muscle tension
• Racing thoughts

However, anxiety-driven restlessness usually comes with emotional symptoms like worry, fear, or dread. Akathisia, on the other hand, often feels more physical and mechanical.

---

3. ADHD

Adults with ADHD may struggle with:

• Sitting through meetings
• Remaining still
• Feeling "driven by a motor"

Unlike akathisia, ADHD-related movement is typically lifelong and not triggered by medication changes (unless stimulant doses are involved).

---

4. Medication Side Effects (Beyond Akathisia)

Other medications can cause jitteriness or restlessness, including:

• Stimulants
• Thyroid hormone replacements
• Decongestants
• Excess caffeine

Always consider recent medication changes if symptoms appeared suddenly.

---

5. Thyroid Disorders

An overactive thyroid (hyperthyroidism) can cause:

• Tremors
• Nervous energy
• Restlessness
• Weight loss
• Rapid heartbeat

A simple blood test can evaluate this.

How to Tell If It Might Be Akathisia

Consider these questions:

• Did symptoms begin after starting or adjusting a medication?
• Do you feel intense discomfort when trying to sit still?
• Is the movement driven by an internal urge rather than just nervousness?
• Does pacing or shifting temporarily relieve the sensation?

If you answered yes to several of these, akathisia becomes more likely.

It's important not to ignore these symptoms, especially if they are new or worsening.

Why Akathisia Should Be Taken Seriously

While akathisia is treatable, it can significantly affect quality of life. People with untreated akathisia may experience:

• Severe distress
• Sleep disruption
• Irritability
• Difficulty functioning at work or home

In more serious cases, untreated akathisia has been linked to worsening depression or impulsive behavior. That's why early recognition and medical care are essential.

This is not about causing alarm — it's about addressing something that can be effectively managed.

Medically Approved Next Steps

If you can't stop moving and it's affecting your daily life, here's what to do:

1. Do Not Stop Medication Suddenly

If you suspect akathisia, do not abruptly stop your medication on your own. Sudden discontinuation can worsen symptoms or cause withdrawal effects.

Instead:

• Contact your prescribing doctor promptly
• Describe your symptoms clearly
• Ask whether akathisia could be the cause

---

2. Schedule a Medical Evaluation

Your doctor may:

• Review your medication history
• Adjust your dosage
• Switch medications
• Prescribe medication to relieve akathisia
• Order blood tests (such as thyroid levels or iron studies)

Akathisia is often managed by lowering the dose, switching medications, or adding specific treatments such as beta-blockers or other supportive medications.

3. Address Possible Restless Leg Syndrome

If symptoms are worse at night or mainly in your legs, consider evaluating for RLS. Iron deficiency is a common contributor, and simple treatment can significantly improve symptoms.

4. Review Lifestyle Factors

While lifestyle changes alone may not fix akathisia, they can reduce overall restlessness:

• Limit caffeine
• Avoid excess alcohol
• Maintain consistent sleep
• Stay physically active during the day
• Practice gentle stretching before bed

These steps support your nervous system and may reduce symptom intensity.

---

5. Monitor Mental Health

Persistent restlessness can affect mood. If you notice:

• Increasing depression
• Hopelessness
• Thoughts of harming yourself
• Severe agitation

Seek immediate medical care or emergency support. These symptoms require urgent attention.

---

When to Speak to a Doctor Immediately

Contact a healthcare professional promptly if:

• Restlessness began after a new medication
• You feel emotionally overwhelmed by the symptoms
• You have chest pain, rapid heart rate, or severe tremors
• You experience thoughts of self-harm

Any symptom that feels severe, rapidly worsening, or life-threatening should be evaluated urgently.

When in doubt, it is always safer to speak to a doctor.

The Bottom Line

If you feel like you can't stop moving, your body is trying to tell you something. The cause may be:

• Akathisia (especially if linked to medication changes)
• Restless Leg Syndrome
• Anxiety
• Thyroid imbalance
• Medication side effects
• ADHD

Akathisia in particular is often misunderstood but very treatable. The key is recognizing it early and working closely with a medical professional.

You do not have to simply "live with it." And you should not try to manage it alone if symptoms are persistent or severe.

Start by observing your symptoms carefully. Consider a structured symptom check if appropriate. Most importantly, speak to a doctor to ensure anything serious or potentially life-threatening is ruled out and properly treated.

Relief is possible — but it starts with the right diagnosis.
