Imagine this: you're sipping coffee, scrolling your phone, and suddenly your body decides to throw a curveball. Maybe your leg trembles, your speech falters, or your thoughts vanish into a fog. If this sounds familiar, you might be navigating the unpredictable terrain of Functional Neurological Disorder—better known as FND.

As someone who’s lived through the ups and downs of FND symptoms, I want to walk you through what it really feels like. Not from a textbook, but from the inside. These symptoms aren’t just medical terms—they’re lived experiences. And if you’re here, you’re probably looking for clarity, connection, and maybe a little comfort.

Let’s dive into the strange, surprising, and often misunderstood world of FND symptoms.

Brain Fog

One of the first symptoms I noticed was brain fog. It’s not just forgetfulness—it’s like your thoughts are stuck in molasses. You try to focus, but everything feels blurry and slow.

You might find yourself rereading the same sentence five times. Or forgetting why you walked into a room. It’s frustrating, especially when you know you’re capable of more.

Brain fog is a common FND symptom, and it can sneak up on you. Some days, you feel sharp and clear. Other days, even simple tasks feel like climbing a mountain.

I’ve learned to be gentle with myself on foggy days. I take breaks, simplify tasks, and remind myself that clarity will return.

Tremors and Involuntary Movements

Have you ever felt your hand twitch or your leg jerk without warning? Tremors are one of the most visible FND symptoms, and they can be downright confusing. Sometimes, my fingers tap a rhythm I didn’t choose. Other times, my arm moves like it’s dancing to music only it can hear. These involuntary movements aren’t painful, but they’re disruptive.

They can happen when I’m relaxed, stressed, or even asleep. And while they’re unpredictable, they’re not dangerous. I’ve learned to explain them to others with humour and honesty. “My body’s just doing its thing,” I’ll say. And slowly, I’ve stopped feeling embarrassed.

Chronic Pain

Pain is one of the most exhausting FND symptoms. It’s not always sharp—it can be dull, aching, or burning. And it moves. One day it’s in your back, the next in your legs.

It’s like having a guest who overstays their welcome. You try everything—heat packs, stretching, rest—but it lingers.

For me, chronic pain made everyday tasks harder. Sitting too long hurt. Standing too long hurt. Even lying down wasn’t always a relief. Seizures strained my muscles in contorted directions. Managing pain with FND means listening to your body. I’ve found that pacing myself, using gentle movement, and practicing mindfulness helps. Pain might be persistent, but it doesn’t define you.

Psychogenic Non-Epileptic Seizures

One of the most misunderstood FND symptoms is Psychogenic Non-Epileptic Seizures (PNES). These episodes look like epileptic seizures but aren’t caused by electrical brain activity. They can involve shaking, collapsing, or losing awareness. And they’re terrifying—especially when people don’t understand them.

I remember my first PNES episode vividly. I felt overwhelmed, then collapsed on the home office floor. I was confused and scared, as was my spouse, and I ended up in an ambulance on the way to the ER. Doctors ruled out epilepsy, and that’s when I learned about FND. PNES is real, and it’s not “just in your head.”

Understanding your triggers—like stress or sensory overload—can help reduce episodes. And having a support system makes all the difference.

Speech Difficulties

Talking should be simple, right? But with FND, speech can become a maze.

Sometimes, I know exactly what I want to say, but the words won’t come out. Other times, my voice sounds shaky or slurred.

It’s like my brain and mouth are out of sync. And it’s frustrating—especially in conversations or public settings. I’ve learned to pause, breathe, and try again. Writing things down helps. So does practicing speech exercises with a therapist.

Gait and Balance

Walking is something most people take for granted. But with FND, each step can feel uncertain. My legs sometimes feel wobbly, like I’m walking on a boat. I’ve stumbled, tripped, and even fallen—without any clear reason.

Balance issues are a common FND symptom, and they can be scary. You might feel dizzy, unsteady, or like your legs have a mind of their own. Using a cane or walker helped me regain confidence. And physical therapy taught me how to move with more control.

Paralysis and Weakness

Imagine trying to move your arm and nothing happens. Or feeling like your legs are made of jelly. Paralysis and weakness are dramatic FND symptoms, and they can come on suddenly. One moment you’re fine, the next you’re struggling to stand.

It’s not that your muscles aren’t strong—it’s that your brain isn’t sending the right signals.

I’ve had days when I couldn’t lift a cup. And others where I felt like I could run a marathon. Recovery is possible, but it takes patience. Rest, rehab, and reassurance are key.

Bladder and Bowel Changes

Let’s talk about something no one wants to discuss—bathroom issues. With FND, your bladder and bowel can become unpredictable. You might feel urgency, frequency, or even incontinence.

It’s embarrassing, but it’s also common. And it’s not your fault.

I’ve had to plan outings around bathroom access. I’ve carried supplies “just in case.” And I’ve learned to talk to my doctor openly. There are treatments, tools, and tips that help. You don’t have to suffer in silence.

Living with FND Symptoms

FND symptoms are like guests at a chaotic party. Some are loud, some are quiet, and some show up uninvited. But here’s the truth: you’re stronger than you think.

Living with FND means learning to adapt, advocate, and accept. It means finding joy in small victories and grace in setbacks.

You’ll meet doctors who understand and others who don’t. You’ll explain your symptoms more times than you can count. But each time, you’ll grow more confident.

I’ve found support in online communities, therapy, and journaling. I’ve cried, laughed, and kept going. And you will too.

Navigating the Journey: What You Can Do

If you’re dealing with FND symptoms, here are a few things that helped me:

• Track your symptoms: Patterns can reveal triggers and guide treatment.

• Find a specialist: Neurologists and therapists familiar with FND are essential.

• Practice self-care: Rest, nutrition, and movement matter more than you think.

• Connect with others: Support groups remind you that you’re not alone.

• Stay curious: Learn about FND, ask questions, and explore new strategies.

Final Thoughts

FND symptoms can feel overwhelming, but they don’t define you. You’re not broken. You’re navigating a complex condition with courage. Every symptom is a clue, not a curse. And every day is a chance to understand your body better.

So welcome to the world of FND. It’s unpredictable, yes—but also full of resilience, discovery, and hope. And if you ever feel lost, remember: I’m here, and so are countless others walking this path with you.
