FAQs About Tick Bite

Here are some frequently asked questions about tick bite.

What does a tick bite look like?

A tick-bite is most readily identified by an engorged tick in the center of a red pattern along the affected skin space. A tick will be anywhere from the size of a pencil eraser to a small grape depending on if it has taken a blood meal from its host.

How long does it take to know if you have Lyme disease?

Firstly, you should not necessarily wait for symptoms of Lyme disease to seek prophylactic treatment in locations with high Lyme disease infestation (endemic). If you suspect a tick bite in the past 72 hours and the tick has been attached for > 36 hours, see a physician. Prophylactic antibiotic treatment for tick bites from Lyme-infested ticks can prevent disability in the future. The most common first sign of actual Lyme disease is a rash, known as erythema migrans, which occurs within seven days of a tick bite.

Do all ticks carry Lyme disease?

No, not all ticks carry Lyme disease, but it is difficult, if nearly impossible to know which ticks carry Lyme disease and which do not. If you suspect a tick bite in the past 72 hours and the tick has been attached for > 36 hours, and you live in a location with high Lyme disease infestation (endemic), see a physician. Prophylactic antibiotic treatment for tick bites from Lyme-infested ticks can prevent disability in the future.

Are tick bites itchy?

Yes, tick bites can itch. They are usually limited to one or two at a time unlike other rashes like chicken pox, etc. Tick bites may also cause pain or tenderness and can be followed by a flu-like illness.

What happens if you don't get the head of a tick when removing it?

The head of the tick may still transmit Lyme disease to a patient and can cause an allergic reaction. It is recommended to use tweezers to firmly grasp the head and twist off. Nails or fingers will often crush the body, leaving the head attached.
