Hi,
There are several possible causes for recurring insect bite-like bumps on arms and legs that appear randomly without any visible bug or bite mark. Some of the most common causes include:
* Allergic reactions: You may be having an allergic reaction to something in your environment, such as certain types of plants, fabrics, or chemicals. These reactions can cause itchy, raised bumps that resemble
insect bites.
* Contact dermatitis: This is a type of
skin inflammation that occurs when your skin comes into contact with an irritant or allergen. Common triggers include poison ivy, cosmetics, and certain fabrics or metals.
* Eczema: Eczema is a chronic skin condition that can cause itchy, red bumps on various parts of the body, including the arms and legs.
* Hives: Hives are itchy, raised bumps that can appear anywhere on the body, including the arms and legs. They can be triggered by a variety of factors, including
stress, medications, and allergic reactions.
* Insect bites or stings: It's possible that you are being bitten or stung by insects that you are not able to see. Some insect bites and stings can cause large, swollen welts that last for several days.
If you are experiencing recurring bumps on your arms and legs, it's best to consult with a healthcare professional to determine the underlying cause and appropriate treatment.
Take care. Hope I have answered your question. Let me know if I can assist you further.
