A Could that tick bite be more than just a nuisance?
Each summer, thousands of Canadians enjoy the great outdoors—often unaware that a single tick bite could lead to something far more serious.

Lyme disease, if caught early, is highly treatable. But the symptoms can be sneaky—sometimes mild, sometimes mistaken for the flu. Knowing what to look for can make all the difference between a quick recovery and months of lingering fatigue, joint pain, or neurological issues.

In this guide, we’ll walk you through the most common early and late-stage Lyme disease symptoms, explain what they might feel like, and help you decide when it’s time to seek medical attention—before the condition becomes harder to manage.

Introduction

Lyme disease is a bacterial infection caused by Borrelia burgdorferi, most commonly spread through the bite of an infected black-legged tick (deer tick). If caught early, Lyme disease can often be treated effectively. However, if left undiagnosed, it can lead to more serious and chronic complications.

Understanding the early and later symptoms is essential to catching the disease before it causes long-term damage. Here’s what to watch for—whether you’ve recently had a tick bite or are experiencing unexplained symptoms.

🟢 Early Lyme Disease Symptoms (3–30 Days After Tick Bite)

In the early stages, Lyme disease typically affects the skin and immune system. Most people don’t feel the tick bite itself, so symptoms are usually the first indication.

Most Common Early Signs:

Erythema Migrans (EM) Rash:
  • A red, expanding rash at the site of the bite.

     

  • May resemble a bull’s-eye with a central clearing.

     

  • Appears in about 70–80% of cases.

     

  • Usually not itchy or painful.

Fatigue:

Unusual tiredness not relieved by rest.

Flu-like Symptoms:

Fever, chills, headache, muscle aches, and swollen lymph nodes.

Neck Stiffness:

Often paired with headache and fatigue

Joint and Muscle Aches:

Especially in larger joints like the knees.

🔶 Later Symptoms of Lyme Disease (Weeks to Months After Infection)

If Lyme disease is not treated in the early stages, the bacteria can spread to the joints, nervous system, and heart, leading to more severe and potentially long-term symptoms.

Later Signs Include:

Severe Joint Pain and Swelling:
  • Especially in knees, elbows, and hips.

     

  • May come and go or become chronic.
Neurological Issues:
  • Numbness, tingling in hands or feet.
  • Facial palsy (drooping on one or both sides of the face).
  • Memory loss, confusion, and difficulty concentrating (“Lyme brain”).
  • Shooting nerve pain or electric-like sensations.

Lyme Carditis (Heart Involvement):
  • Irregular heartbeat or palpitations.

     

  • Chest pain or shortness of breath.

     

  • Dizziness or fainting.
Migrating Pain:

Pain that moves between joints, tendons, or muscles.

Mood or Sleep Disorders:

Anxiety, depression, or insomnia can develop or worsen

🟠 Persistent Lyme Disease Symptoms (Chronic or Post-Treatment Phase)

In some individuals, symptoms persist long after antibiotic treatment. This is sometimes referred to as Chronic Lyme Disease or Post-Treatment Lyme Disease Syndrome (PTLDS).

Common Persistent Symptoms Include:

  • Chronic fatigue

  • Ongoing joint or muscle pain

  • Cognitive difficulties (brain fog)

  • Sleep disturbances

  • Mood changes or depression

  • Sensitivity to light or sound

 

🧪 What to Do if You Suspect Lyme Disease

  1. See a Healthcare Provider Promptly:
    Blood tests are more reliable a few weeks after exposure. However, diagnosis is often clinical (based on symptoms and history).

  2. Start Treatment Early:
    The earlier you begin antibiotics, the better the outcome.

  3. Monitor Your Symptoms:
    Keep a journal of new or ongoing issues.

Frequently Asked Questions About Lyme Disease Symptoms:

Can Lyme disease cause brain tumors?

No, Lyme disease does not cause brain tumors. However, it can lead to neurological complications like brain inflammation, facial palsy, or cognitive dysfunction. These symptoms may sometimes be mistaken for other brain conditions, so a thorough medical evaluation is important.

Can Lyme disease cause CIDP (Chronic Inflammatory Demyelinating Polyneuropathy)?

Lyme disease has not been proven to directly cause CIDP, but it can lead to peripheral neuropathy, which presents with similar symptoms like numbness, weakness, and tingling. A neurologist can help determine the exact cause.

Can Lyme disease cause demyelination?

Yes, demyelination (damage to the protective covering of nerves) can occur in rare cases of neuroborreliosis, an advanced form of Lyme disease affecting the central nervous system. This can lead to neurological symptoms like numbness, weakness, and cognitive issues.

Can Lyme disease cause diarrhea?

Yes. While not a hallmark symptom, Lyme disease can cause gastrointestinal symptoms in some individuals, including diarrhea, especially during the early systemic infection stage or as a side effect of antibiotics used in treatment.

 

Can Lyme disease cause foot pain?

Yes. Joint pain and nerve pain in the feet and lower legs are common, especially in chronic Lyme disease. This may feel like burning, stabbing, or aching sensations.

Can Lyme disease cause gastroparesis?

Though rare, Lyme disease may contribute to autonomic nervous system dysfunction, which in turn could affect gastrointestinal motility and lead to symptoms like gastroparesis (delayed stomach emptying). This is not common but has been reported anecdotally.

Can Lyme disease cause hearing loss?

Yes. Some patients experience temporary or partial hearing loss related to nerve inflammation. This may also be accompanied by tinnitus (ringing in the ears) or vertigo in more advanced cases.

Can Lyme disease cause heart problems?

Yes. Lyme carditis is a known complication where the infection affects the heart’s electrical system. This can cause irregular heartbeat, chest pain, palpitations, or even fainting.

Can Lyme disease cause iron deficiency?

Lyme disease itself does not typically cause iron deficiency, but chronic inflammation may affect iron metabolism, and symptoms like fatigue can overlap. Bloodwork is needed to determine the cause.

Can Lyme disease cause joint pain?

Absolutely. Joint pain is one of the most common symptoms, especially in the knees, hips, and elbows. The pain may migrate or flare intermittently and can persist for months if untreated

Can Lyme disease cause kidney problems?

Lyme disease rarely affects the kidneys in humans, though it can in dogs. However, any unusual urinary symptoms or lower back pain should be evaluated by a physician.

Can Lyme disease cause lesions on the brain?

In rare neurological cases, Lyme disease may result in white matter lesions on brain imaging. These can sometimes mimic the appearance of multiple sclerosis (MS), which is why accurate testing and diagnosis are essential.

Can Lyme disease cause Meniere’s disease?

Lyme disease doesn’t directly cause Meniere’s disease, but it can produce similar symptoms such as vertigo, hearing loss, and tinnitus. It’s important to rule out Lyme if you’re experiencing these symptoms, especially with a history of tick exposure.

Can Lyme disease cause multiple sclerosis (MS)?

Lyme disease and MS are separate conditions, but Lyme can sometimes mimic MS symptoms, including nerve pain, weakness, and lesions on brain scans. Proper diagnostic testing is needed to differentiate between the two.

Can Lyme disease cause muscle cramps?

Yes. Muscle cramps and spasms can occur due to inflammation or nerve involvement in Lyme disease. These may affect sleep or daily function in chronic cases.

Can Lyme disease cause OCD (Obsessive Compulsive Disorder)?

There is no direct link between Lyme and OCD, but Lyme can impact the nervous system and cause anxiety, intrusive thoughts, and mood disorders. These symptoms may feel similar to OCD and should be assessed by a mental health professional.

Can Lyme disease cause permanent nerve damage?

If left untreated or undertreated, Lyme disease can cause lasting nerve damage, particularly in the form of peripheral neuropathy or facial nerve paralysis. Early treatment is key to avoiding long-term complications.

Can Lyme disease cause psoriasis?

Lyme disease does not directly cause psoriasis, but the immune system disruption it creates may trigger autoimmune skin conditions in genetically predisposed individuals.

Can Lyme disease cause short-term memory loss?

Yes. Short-term memory problems, brain fog, and difficulty concentrating are common neurological symptoms in later stages of Lyme disease.

Can Lyme disease cause staph infections?

No. Staph infections are caused by a different type of bacteria. However, if Lyme disease weakens your immune system or if you have open skin wounds, the risk of other infections may increase.

Can Lyme disease cause stiff neck?

Yes. A stiff neck is a common early symptom, especially if Lyme disease progresses to involve the meninges (protective layers around the brain and spinal cord).

Can Lyme disease cause tinnitus?

Yes. Tinnitus (ringing in the ears) is sometimes reported, especially when Lyme affects the cranial nerves or inner ear.

Can Lyme disease cause tremors?

In some cases, neurological Lyme disease can lead to tremors or muscle twitching, especially if the brain or spine is affected.

Can Lyme disease cause vasculitis?

Though rare, Lyme disease may trigger inflammation of the blood vessels (vasculitis), especially in cases where the immune system is significantly impacted.

Can Lyme disease cause vertigo?

Yes. Vertigo and dizziness are potential neurological symptoms of Lyme disease and may also result from inner ear inflammation.
