According to Healthline, the typical sign of a tick bite is seeing a tick attached to the skin. A tick remains on the skin for several days or weeks while sucking blood from the body before detaching. Ticks leave singular marks, which may become red or swell.
Healthline states that if one is allergic to tick bites, a rash, blisters or swelling may occur at the tick bite site.
Kid’s Health states that if one is bitten by a disease-carrying tick, a red bump surround by a red rash is a sign of Lyme disease, and red dots in spotted fashion on the ankle or the wrist may signify Rocky Mountain spotted fever.
