What are the red spots on the skin?
Red spots on the skin can be caused by a variety of conditions, including infections, allergic reactions, and inflammatory processes. Red spots appear anywhere on the body.
The red spots may be harmless or benign or may be a sign of a serious illness such as leukaemia. Red spots on the skin can appear suddenly or develop over a long period of time, depending on the underlying disease, disorder, or condition. The red spots can vary in size from small to large and cover a significant area of the body from small to large. The red spots are itchy or painful, flattened or enlarged, and vary in colour from pink to bright red to purple to red.
The tiny, red, pointed spots called petechiae are caused by broken blood vessels under the skin and indicate a life-threatening condition such as meningitis. The red spots may include redness of the neck, alertness, high fever, difficulty breathing, bloody stools, or swelling of the face or tongue.
Symptoms of red spots on the skin
Red spots on the skin are a common medical problem. When scars occur on the spread, they are sometimes called a rash. Rashes can be caused by skin infections, contagious infections (spread all over the body), allergic reactions, or skin irritation.
When the red bump or rash is flat, it is medically called a macula. When the red spot grows, it is called a papule. Erythema is the medical term for the redness of the skin. Red spots on the skin A small, benign tumor in a blood vessel called a hemangioma.
Small, spikey bleeding can be seen on the skin and is called petechiae. Bleeding defects can lead to the formation of large red spots called purpura. The rash is associated with other symptoms such as hives or itching. Red spots on the skin associated with underlying medical conditions are associated with symptoms of the underlying disease.
Causes of red spots on the skin
There are many causes of itchy red spots on the skin.
- Angiomas: Angiomas are skin growths that occur anywhere on the body. These are fused with blood vessels and look like red dome bumps, also called papules, on or under the skin.
- Bolis: A boil is an infection of the skin of the hair follicle or sebaceous gland. It is usually a red bump, often filled with pus. Boils usually disappear after bursting and the pus or liquid dries up.
- Keratosis pilaris: Keratosis pilaris is a benign skin condition caused by the overproduction of a protein called keratin. It causes small, tight bumps around the hair follicles, especially around the thighs, buttocks, and upper arms.
- Birthmarks: Birthmarks are pigmented spots on our skin that appear at birth or soon after. Sometimes these spots are red. In this case, they are usually vascular birthmarks. Abnormal blood vessels in the skin can cause these types of birthmarks.
- Allergic reaction: One of the most common causes of red spots on the skin is a rash caused by allergic reactions. The reaction can be a large amount of food, pollen, or other allergens in the air, cosmetics, skincare products, laundry detergent, or other irritants. A doctor can perform a patch test to reveal which allergens are triggering the reaction on your skin.
- Pityriasis rosea: Pityriasis rosea is a rash caused by a virus and usually lasts between six and twelve weeks. It has a large “mother” patch with small patches around it. These rashes are usually pink or red in colour and can flare and flake.
- Blood spots: Petechiae, or bloodstains, are round, red spots that occur as a result of small blood vessels. They are flat to the touch and sometimes appear rashes. These can occur for various reasons such as bruising, strain, and sunburn.
- Irritant contact dermatitis: Irritant contact dermatitis is a rash caused by irritation from a substance. Unlike rashes caused by an allergic reaction, they are not caused by irritation of immune origin. Instead, it’s usually caused by exposure to mild irritants such as soaps, detergents, or an acid or alkali.
