Fleas are small insects that feed on warm-blooded humans and animals. Most people may not even know fleas have invaded their homes. So, it is necessary to recognize the signs and symptoms of a flea bite that could produce painful skin rashes and allergic reactions.

Rash

People with flea bites typically develop a rash or hives. The small bumps are often red and turn white when pressed. Some people notice the pattern of the bites includes a cluster of three bumps together. The most common areas of the body for flea bites include the waist, armpits, ankles, and the bends of the knees and elbows.

Itching

Flea bites may not always produce bumps or hives. An indication of a bite may include itching, similar to the itchy sensation caused by mosquitoes. Itching that occurs in conjunction with small spots on the skin indicates fleas have bitten the body. People who itch the site of the bite may experience bleeding.

Swelling

Existing sores or injuries on the skin are susceptible to infection. People with flea bites may notice swelling near existing wounds or sores in addition to a rash, hives, or itching.

Red Halo

Flea bites commonly occur in clusters. One way to distinguish a flea bite from another insect bite is to identify the red halo within the bite center. Between the small, red bumps, a halo-like appearance forms at the site of the bite.

Blisters

Most people recover relatively quickly from flea bites as they disappear on their own. People who itch the bites excessively may develop white-topped blisters. These blisters could be an indication that an infection exists in the body. If blisters form, see your doctor.

Allergic Reactions

Individuals who have allergic reactions to flea bites may experience severe symptoms that require immediate medical attention. General signs of an allergic reaction to flea bites include dizziness, nausea, chest pain, or difficulty breathing. In rare cases, people can feel swelling of the tongue or lips.

Swollen Glands

An infection stemming from flea bites can produce swollen glands in rare cases. Swollen glands accompany pain in the area and redness on the skin. If these symptoms develop, see your doctor.
