I have a red pimple. What caused it?

Red pimples broke out on my body, which did not hurt or itch. Folliculitis and urticaria are common. This article will introduce the symptoms and treatment of these two diseases to help you better understand the causes of red pimples.

folliculitis

Folliculitis is an inflammation caused by bacterial or fungal infection, which can be single or multiple. It hurts when the redness is serious, but it doesn't hurt when it is lighter.

urticaria

Urticaria is commonly known as rash. It is a localized edema reaction caused by the expansion and permeability increase of small blood vessels in skin and mucosa, which generally subsides within 2 ~ 24 hours. Fading is not healing, but it will recur.

Diet regulation

It is recommended to observe more, eat lightly and avoid spicy and greasy food and seafood products.

Dermatological visit

If the symptoms are serious, see a dermatologist and don't take medicine without knowing the cause.
