Ticks are tiny parasites that feed on the blood of humans and animals, often found in grassy, wooded, or outdoor areas. Because their bites are usually painless, they can stay attached for hours or even days without being noticed.

Once attached, a tick locks onto the skin and begins feeding. The bite may appear as a small red bump with mild itching or irritation, but the main concern is the potential transmission of infections.

The longer a tick remains attached, the higher the risk of disease in some cases. Prompt and careful removal, along with cleaning the area, can help reduce complications.

After a bite, it’s important to monitor symptoms over time. While mild redness can be harmless, signs like fever, fatigue, headaches, muscle aches, or swollen lymph nodes may indicate a problem.

A spreading rash is especially important to watch for, as it can signal illnesses such as Lyme disease.

Ticks can also carry other diseases, including Rocky Mountain spotted fever, ehrlichiosis, anaplasmosis, babesiosis, and tick paralysis.

Certain symptoms should not be ignored, such as increasing pain, swelling, warmth, or pus at the bite site, along with severe headaches, joint pain, or unusual exhaustion.

Emergency care may be needed if symptoms like breathing difficulty, chest pain, paralysis, severe weakness, or neurological changes develop after a tick bite.
