Tick bites don’t always lead to Lyme, but when they do, early symptoms matter. What’s one thing you wish more people knew?

Most people don’t think twice about a tick bite.
They pull it out, maybe dab on some antibiotic ointment, and move on. After all, not every tick carries Lyme disease. Not every bite leads to illness. That’s what we tell ourselves.
But in my practice, I’ve seen what happens when it does lead to something more. The hardest part? It’s not always obvious—at least, not at first.

“It was just a bug bite—until it wasn’t.”
One of my patients came in because her daughter had what she thought was a spider bite. A week later, the red mark had spread. It wasn’t itchy or painful. Just… odd. Then came the fever. Fatigue. A kind of tiredness that sleep didn’t fix. That’s when she remembered the tick.
They hadn’t saved it. They didn’t think they needed to.
The rash she had? That expanding red circle? It’s called erythema migrans—a classic early sign of Lyme disease. But here’s the catch: not everyone gets that rash. Some people never see anything at all.

Early symptoms matter—but they’re easy to miss.
After a tick bite, the signs can feel vague:
A headache that won’t go away.
Feeling unusually tired.
Sweating through the sheets at night.
A sore knee that doesn’t match any recent injury.
It doesn’t scream “infection.” But for someone living in a tick-endemic area, those subtle signs may be the first whispers of something serious.
Ticks can carry more than just Lyme disease. Babesia, for example, is a parasite, not a bacteria, and causes fever, chills, and fatigue that mimic malaria. Bartonella might lead to burning pain in the feet, cognitive changes, or skin streaks that resemble stretch marks. None of these start with drama. They start with discomfort—and delay.

The nervous system can get involved, too.
Another patient—a high schooler—came to me months after his initial tick bite. He was struggling to keep up in school. Couldn’t focus. Complained of numbness in his hands and feet. His parents had taken him to a neurologist, then a psychiatrist. They even wondered if it was anxiety.
But he also had night sweats. Fatigue. Trouble sleeping. And it all started after that tick bite last summer.
Infections like Lyme and co-infections such as Bartonella and Babesia can affect the nervous system, causing brain fog, dizziness, and even mood changes. These symptoms are easy to attribute to other things—until they don’t go away.

Sometimes it even reaches the heart.
Lyme carditis is rare, but it happens. I’ve seen it in otherwise healthy people:
A young man with palpitations so strong he could feel them in his throat.
A woman in her 50s who fainted in the grocery store—no warning, no previous heart issues.
A teenager who struggled to keep up in soccer after weeks of chest tightness.
In each case, Lyme disease had disrupted the heart’s electrical system. None of them knew that a tick bite months earlier could cause that.

What if you don’t remember the bite?
That’s common. Ticks are small—some the size of a poppy seed—and bites are often painless. Many patients don’t know they were bitten at all. They don’t connect their symptoms to ticks until weeks or months later, when the diagnosis finally comes into focus.
That’s why we don’t just ask, “Did you see a tick?”
We ask, “Have you had unexplained symptoms—fatigue, pain, brain fog, heart palpitations—after spending time outdoors?”

So what should you do after a tick bite?
If a rash appears—especially one that expands—get it checked. If you experience fever, chills, joint pain, or anything that feels like the flu but lingers, don’t wait. If you start to feel off in ways you can’t explain—neurological or heart-related symptoms in particular—trust your instincts.
And even if you don’t remember a bite, but you live in or visited an area with ticks, and now you don’t feel like yourself? That’s worth investigating.

The bottom line
Most tick bites are harmless.
But some aren’t—and when infection sets in, time matters.
The earlier we catch Lyme disease (and related infections), the better the outcome. The longer it lingers untreated, the more likely it spreads—into joints, nerves, and even the heart.
So check yourself. Check your kids. Check your pets.
Know the signs. Listen to your body.
And most of all—don’t dismiss symptoms that don’t go away.
