Internal Shaky Feeling in the Body: Causes, Care, and When to Seek Help

Disclaimer: This article is for general information only and isn’t medical advice or a diagnosis. If you have severe symptoms or think it may be an emergency, call your local emergency number.

Ever feel like your whole body is shaking on the inside, but when you look down, nothing is actually moving? You’re not crazy. You’re also not alone.

That strange, buzzy, vibrating, or shaky feeling inside the body is a common symptom people struggle to describe and then immediately worry is something serious.

Let’s walk through what might be going on, when to relax, when to call a doctor, and what you can do today to calm the internal shakes.

What Does a “Shaky Feeling Inside” Actually Feel Like?

Everyone explains this a little differently, but common descriptions include:

  • “My whole body feels like it’s humming or buzzing inside.”
  • “I feel like I’m trembling internally, but I don’t see my hands shaking.”
  • “It’s like I drank way too much coffee, even when I didn’t.”
  • “I wake up feeling like I’m vibrating.”

It might show up as:

  • Internal tremor or vibration
  • Slight jitteriness or restlessness
  • A sense of weakness or wobbly legs
  • Feeling like your insides are shaking during or after stress

Key point: Internal shakiness can be real even if no one else can see it.

Common Non-Emergency Reasons You Might Feel Shaky Inside

There are many possible causes, some physical, some related to stress and anxiety, and sometimes a mix of both. Here are some of the more common, non-emergency ones.

1. Anxiety, Panic, and the Body’s Stress Response

When you’re anxious or having a panic attack, your body releases stress hormones like adrenaline and cortisol. That can:

  • Speed up your heart rate and breathing
  • Make your muscles tense
  • Cause sweating and a shaky or jittery feeling

According to major health organizations, symptoms of anxiety and panic commonly include trembling or shaking, feeling keyed up, sweating, pounding heart, and a sense of impending doom.

Sometimes the shaking is mostly internal. You feel like you’re vibrating inside without dramatic visible tremors.

Mini example:

You’re sitting on the couch scrolling your phone. You read an upsetting message, and suddenly you feel:

  • A rush of heat
  • Heart pounding
  • Stomach flip
  • Weird internal buzzing in your chest or limbs

That’s your fight-or-flight system turning on, even if you’re literally just sitting still.

Takeaway: Anxiety and panic can absolutely cause a shaky feeling inside the body, even if no one else notices anything.

2. Too Little Food, Low Blood Sugar, or Long Gaps Between Meals

If you haven’t eaten for a while, or you’ve had mostly sugar with no protein or fat, your blood sugar can drop. Many people feel:

  • Shaky or jittery
  • Weak or lightheaded
  • Sweaty or clammy
  • Irritable or anxious

Gently raising blood sugar (for example with a snack that includes carbs and protein, like an apple with peanut butter) often helps within 15–20 minutes.

Mini example:

You skip breakfast, grab coffee, have a donut at 11 AM, and by 1 PM you feel:

  • Shaky inside
  • Anxious for no clear reason
  • A bit nauseous

Your body may be asking for more stable fuel.

Takeaway: If your internal shakiness improves after eating, especially regularly, it’s worth talking to a healthcare provider about blood sugar patterns and worth prioritizing regular meals.

3. Caffeine, Energy Drinks, and Stimulants

Caffeine (coffee, tea, sodas, energy drinks, pre-workout powders) and certain medications can overstimulate your nervous system.

Common effects when you’ve had too much or are sensitive include:

  • Internal trembling or jitteriness
  • Racing heart
  • Restlessness
  • Trouble sleeping

Sensitivity varies a lot. For some, even one strong cup or a new energy drink can trigger internal shakes.

Takeaway: If your inner shakiness is worse after caffeine or stimulant medications, track that pattern and discuss it with your doctor or prescriber.

4. Dehydration and Electrolyte Imbalance

Being low on fluids and minerals like sodium, potassium, or magnesium can affect your muscles and nerves.

You might notice:

  • Feeling weak, shaky, or off
  • Muscle cramps or twitches
  • Headache
  • Dizziness when standing up

This can happen after intense sweating, stomach bugs with vomiting or diarrhea, or simply not drinking enough fluids all day.

Takeaway: Consistent hydration and balanced meals usually help, but ongoing or severe symptoms should be checked by a healthcare professional.

5. Poor Sleep or Sudden Stress Overload

When you’re sleep-deprived or emotionally overwhelmed, your nervous system can get stuck in a hyper-alert state. That may feel like:

  • Internal vibrating or buzzing
  • Feeling wired but tired
  • Startling easily
  • Brain fog and irritability

Mini example:

You pull a late night, get 4 hours of sleep, then wake up to a stressful email. Your body may respond with:

  • Internal trembling
  • Tight chest
  • Racing thoughts

Takeaway: Your nervous system benefits from rhythm: regular sleep, regular meals, regular movement. When that’s off, shaky sensations often get louder.

Other Medical Causes That Can Include Internal Shaking

There are less common but important medical causes that can come with shakiness, tremors, or internal vibration. These need proper evaluation by a healthcare professional.

Some possibilities doctors think about include:

  • Thyroid problems (like overactive thyroid), which can cause tremor, weight loss, sweating, and fast heart rate.
  • Medication side effects or withdrawal, including some antidepressants, anti-anxiety meds, asthma medicines, and others.
  • Neurologic conditions that can cause tremors or internal vibration.
  • Metabolic or hormone issues, like low blood sugar in diabetes.
  • Substance use or withdrawal, including alcohol.

The same symptom, like a shaky feeling inside the body, can be caused by very different things. That’s why professional evaluation matters, especially if it’s new, frequent, or worrying you.

Takeaway: Don’t self-diagnose. Use your symptom as a signal to get the right help, not as a search rabbit hole.

When Is a Shaky Feeling Inside the Body an Emergency?

Internal shakiness by itself is often not an emergency, especially if it’s familiar, mild, and comes with anxiety or hunger.

But you should seek urgent or emergency care if the shaky feeling comes with any of these red-flag symptoms:

  • Chest pain, pressure, or tightness
  • Trouble breathing or feeling like you can’t get enough air
  • Suddenly feeling confused, very drowsy, or not making sense
  • Weakness or numbness in the face, arm, or leg (especially on one side)
  • Trouble speaking, slurred speech, or difficulty understanding others
  • Sudden severe headache, described as the worst headache of your life
  • Fainting or nearly fainting
  • Very fast, irregular, or pounding heartbeat that doesn’t settle, or feeling like you might pass out
  • Shaking along with high fever, stiff neck, or feeling very unwell

If you’re in doubt, it is always okay to seek urgent help or call your local emergency number.

Takeaway: Shaky plus big red-flag symptoms means you should get urgent medical care.

How to Talk to Your Doctor About Your Internal Shakiness

Walking in and saying “I feel weird and shaky inside” can be hard to explain. A few specifics can really help your provider.

Before your appointment, jot down:

  1. When it started
    Was it sudden or gradual? A one-time thing or ongoing?

  2. How often it happens
    Daily? Only during stress? At night? After certain foods or drinks?

  3. What makes it better or worse
    Does it improve after eating, drinking water, resting, or breathing exercises? Worse with caffeine, stress, standing up, or lying down?

  4. Other symptoms that show up with it
    Heart racing, dizziness, sweating, chest discomfort, nausea, muscle twitching, and similar symptoms.

  5. Your current meds and supplements
    Include prescriptions, over-the-counter meds, herbal products, and energy drinks.

You might say something like:

For the past three weeks, I’ve had episodes where my body feels like it’s shaking inside for about 10–20 minutes. It happens mostly in the morning, sometimes with a racing heart. I drink two coffees a day. It seems a bit better after eating. I’m worried something is wrong.

That gives your clinician a starting point for questions, exam, and possible tests.

Takeaway: The more specific you can be about your symptoms and patterns, the easier it is for your provider to help.

What You Can Try at Home (Without Self-Diagnosing)

These ideas are not a replacement for medical care, but they’re often general habits that can calm a sensitive nervous system and reduce internal shakiness.

1. Check Your Basics: Food, Water, Sleep

  • Eat regularly. Aim for meals or snacks every 3–4 hours while awake.
  • Include protein and fiber. They help keep blood sugar steadier. Examples include eggs and toast, yogurt and fruit, nuts, beans, lean meats, tofu, and whole grains.
  • Hydrate. Sip water through the day. If you’ve been sweating a lot or sick, consider an oral rehydration solution or electrolyte drink, unless your doctor told you to limit fluids or salt.
  • Prioritize sleep. Many adults do best in the 7–9 hour range. Consistent bed and wake times help.

Takeaway: Basic habits can sometimes meaningfully reduce symptoms.

2. Experiment With Reducing Stimulants

  • Cut back on caffeine gradually if you notice your inner shakiness spikes after coffee, tea, soda, pre-workout, or energy drinks.
  • Avoid new high-dose energy drinks or supplements that promise extreme focus or intensity.
  • If you’re on prescription stimulants, for example for ADHD, don’t change doses on your own. Instead, tell your prescriber about the shaky feeling.

Takeaway: Less stimulant input often means less internal vibration.

3. Use Grounding and Calming Techniques in the Moment

When that shaky feeling hits, it’s easy to panic, which usually makes it worse. Try:

  • Slow, deep breathing. Inhale through your nose for 4 seconds, hold for 2, exhale slowly for 6–8. Repeat for a few minutes.
  • Grounding with your senses. Name 5 things you can see, 4 things you can feel, 3 you can hear, 2 you can smell, and 1 you can taste.
  • Gentle movement. A short walk, light stretching, or shaking out your limbs can release some built-up body tension.

If the shakiness is anxiety-related, these often dial it down.

Takeaway: You may not control when symptoms show up, but you can build a toolbox for what you do next.

4. Consider Your Mental Health, Not Just Your Physical Health

Internal shakiness lives at the intersection of body and mind. Even when it isn’t only anxiety, anxiety often appears once the symptom shows up and fear can keep the cycle going.

Helpful options to discuss with a professional might include:

  • Therapy, such as cognitive behavioral therapy, to work with health anxiety or panic
  • Stress-management skills, such as mindfulness, breathing practices, and nervous-system regulation
  • Medication if appropriate and prescribed

Takeaway: It’s not all in your head, but your mind is a powerful partner in how your body feels.

When Should You Absolutely See a Doctor About Internal Shakiness?

You should book a visit with a healthcare provider if:

  • The shaky feeling inside your body is new, lasts more than a few days, or keeps coming back.
  • It’s getting worse over time instead of slowly improving.
  • It interferes with sleep, work, or daily life.
  • You have other symptoms like unintentional weight loss, fever, persistent fast heart rate, new tremors people can see, or changes in movement or speech.
  • You have a medical condition such as diabetes, thyroid disease, heart disease, or a neurologic condition and something feels different from your usual.

Takeaway: If your instinct says, “This doesn’t feel right,” that alone is a good enough reason to get checked.

Final Thoughts: You’re Not Making It Up

An internal shaky feeling can be uncomfortable, scary, and hard to explain, but it is a real experience that deserves attention and care.

  • Sometimes it’s a stressed, tired, or over-caffeinated nervous system.
  • Sometimes it’s anxiety or panic showing up in the body.
  • Sometimes it’s a medical issue that needs treatment.

Your job isn’t to diagnose yourself. Your job is to notice, track, and speak up.

You’re allowed to ask questions. You’re allowed to say, “Something feels off.” And you are allowed to get help.
