Beyond the Basics: Unusual Symptoms of Lyme Disease You Need to Recognize

Have you been experiencing strange symptoms lately, such as fatigue, joint pain, and headaches? If you live in a wooded or grassy area, you might have contracted Lyme disease, a bacterial infection that’s transmitted through tick bites. While most people know the classic signs of Lyme disease, such as a bull’s eye rash and fever, there are less typical symptoms that can be easily overlooked but are just as significant. In this article, we’ll explore some of these unusual signs of Lyme disease and how to recognize them early.

1. Bell’s Palsy

One symptom that might surprise you is facial paralysis, also known as Bell’s palsy. This condition occurs when the cranial nerve that controls facial muscles becomes inflamed, leading to drooping or weakness on one side of the face. While Bell’s palsy can be caused by many factors, including viral infections, Lyme disease is one potential trigger. In fact, studies suggest that up to 10% of Lyme disease patients experience Bell’s palsy as a complication. If you notice sudden facial drooping, seek medical attention right away.

2. Cognitive Impairment

Another unusual symptom of Lyme disease is cognitive impairment, or “brain fog.” This can manifest as difficulty concentrating, memory problems, and disorientation. A study published in the Archives of Clinical Neuropsychology found that 23% of Lyme disease patients had cognitive impairment. In some cases, this symptom may persist even after other symptoms have resolved. Don’t dismiss cognitive symptoms as stress or aging; consider them a warning sign of Lyme disease.

3. Heart Palpitations

While heart palpitations are a common symptom of anxiety, they can also indicate Lyme disease. This is because the bacteria that cause Lyme disease can affect the electrical conduction system of the heart, leading to abnormal heart rhythms and palpitations. If you experience heart palpitations that are not related to stress or exercise, mention them to your doctor and get tested for Lyme disease.

4. Vision Changes

Lyme disease can affect various parts of the eye, leading to vision changes such as blurred or double vision, sensitivity to light, and eye pain. These symptoms may be due to inflammation of the optic nerve or other structures in the eye. If you notice any changes in your vision, especially if they’re sudden or persistent, see an eye doctor to rule out Lyme disease as a cause.


Lyme disease can present itself in unusual ways that are not always easy to diagnose. That’s why it’s important to be aware of the less typical symptoms and seek medical attention if you experience any of them. Remember, prevention is key: avoid tick-infested areas, wear protective clothing and repellent, and check your skin for ticks after spending time outdoors. Stay vigilant and stay healthy.
