What is small nonitchy red bites that are all over my feet and legs?

Potential Causes of Small, Non-Itchy Red Bites on Feet and Legs:

Insect Bites: These bites may be caused by insects like fleas, bed bugs, or mites, which are common pests in homes, hotels, and outdoor environments.

Chiggers: Chiggers are tiny mites that inject an irritant into the skin, causing small red bumps and intense itching. They are often found in grassy areas.

Spider Bites: Some spider bites can cause small red bumps or marks on the skin. However, it's essential to note that most spider bites are not dangerous and heal on their own.

Allergic Reactions: Certain individuals may experience allergic reactions to insect bites, resulting in small red bumps or hives on the skin.

Contact Dermatitis: An allergic reaction to plants, chemicals, or other substances that contact the skin can lead to red bumps or rashes on the feet and legs.

Heat Rash: Also known as miliaria, heat rash occurs when sweat ducts become clogged, trapping sweat under the skin. This can cause small, non-itchy red bumps on the skin, often in areas prone to sweating.

Medications: Certain medications, such as antibiotics, can cause skin reactions, including red bumps or rashes on the feet and legs.

If you are concerned about the bites or they persist, it's best to consult a healthcare professional for proper diagnosis and treatment.
