What causes red spots on the body?
Disease description:
Recently, I noticed the appearance of many small red spots on my body. Initially, I thought they were caused by insect bites, but over time, these red spots did not fade away; instead, they have been increasing in number. The spots are mainly distributed on the arms and legs, and are occasionally accompanied by mild itching. I am 30 years old, generally in good health, with no history of allergies, nor have I been exposed to any particular substances.

Having red spots on the body is a common skin symptom that may be caused by various factors. These causes include, but are not limited to, allergic reactions, skin inflammation, viral infections, bleeding disorders, and malignant tumors. Allergic reactions are usually triggered by exposure to allergens such as pollen, dust mites, foods, or medications, leading to symptoms like red spots and itching on the skin. Skin inflammations such as eczema and dermatitis can also cause red spots on the body. These inflammations are typically caused by a combination of internal and external factors, such as dry skin, friction, and irritation from chemical substances. Additionally, certain viral infections, such as measles and rubella, may also result in red spots appearing on the body, often accompanied by systemic symptoms.
Patients are advised to seek timely medical attention from a dermatologist for thorough examination and evaluation. Prior to the appointment, one can try documenting the progression of the red spots, including the time of first appearance, changes in distribution, and whether there are any accompanying symptoms. This information will help the doctor make a more accurate diagnosis.
