Can Tick Bites Cause a Fever? When to Get Checked for Lyme Disease

April 27, 2025

Tick bites can sometimes lead to more than just an itchy spot on the skin. They can trigger serious health concerns, including fever. While not every tick bite causes illness, some ticks carry bacteria that can infect humans, leading to conditions like Lyme disease. A fever after a tick bite may be an early warning sign of infection, especially if it's accompanied by other symptoms such as fatigue, joint pain, or a distinctive bull's-eye rash. Understanding when a fever is cause for concern and knowing the signs of Lyme disease can help ensure timely diagnosis and treatment.

How To Identify Tick Bites

Identifying a tick bite can be tricky because it is often painless and may go unnoticed at first. However, several signs can help you recognize one. A typical tick bite appears as a small, red bump, similar to a mosquito bite, and it may be slightly swollen or itchy. Sometimes, you might still find the tick attached to the skin.

One of the key indicators to watch for is a rash that develops around the bite site, particularly the bull's-eye rash, a hallmark of Lyme disease. This rash usually appears a few days to weeks after the bite and features a red center surrounded by a clear area and a red outer ring. Monitoring the bite area for changes in size, color, or symptoms like pain, swelling, or fever is essential in identifying and responding to a potentially harmful tick bite.

Tick Bite Symptoms

Tick bite symptoms can vary depending on the type of tick and whether it transmits any diseases. A tick bite often causes only mild symptoms like redness, itching, or slight swelling at the bite site. However, more serious symptoms can develop if the tick carries an infection, such as Lyme disease, Rocky Mountain spotted fever, or ehrlichiosis.

Common symptoms to watch for include:

  • Fever and chills
  • Fatigue or muscle aches
  • Headache
  • Joint pain or stiffness 
  • Swollen lymph nodes 
  • Rash, especially a bull's-eye-shaped rash associated with Lyme disease

Diagnosing Lyme Disease

Testing for Lyme disease involves monitoring symptoms, reviewing possible exposure to ticks, and undergoing medical testing if necessary. The first step is to be aware of early warning signs, such as a circular eye rash, fever, fatigue, muscle aches, and swollen joints. These symptoms usually appear within 3 to 30 days after a tick bite.

If you experience these signs, especially after spending time in wooded or grassy areas where ticks are common, you should consult a healthcare provider. Doctors typically diagnose Lyme disease based on your medical history, symptoms, and whether you've been in areas where infected ticks are found. Sometimes, they may order blood tests to confirm the diagnosis.
