Why do I get tiny, isolated red spots on the arms and chest?

Hi,

Welcome to icliniq.com.

The red spots over your skin could be due to petechiae. Petechiae are tiny red, flat spots that appear on your skin. They are caused by bleeding. They can sometimes be multiple and may appear as a rash. Do you get bruised easily, or does your blood take long to clot when you get a cut? Do you have any enlarged lymph nodes?

Hi,

Welcome back to icliniq.com.

We can rule out bleeding disorders (usually, a normal platelet count and bleeding and clotting time estimation are done if you have easy bruisability) since you said that you do not take longer than the usual time for blood clotting. It should be a cherry angioma. I would suggest a dermoscopy to identify the condition. Few petechiae can be formed when tiny blood vessels called capillaries break open. It can occur due to damage to the skin, such as from blunt force. Friction against the skin from carrying a heavy bag or backpack or a tight strap from clothing can lead to petechiae. Sunburn can also cause petechiae. It can also be caused by less intake of vitamin C in your diet. I would suggest the following. Incorporate fruits rich in vitamin C in your diet like cantaloupe, citrus fruits, and juices such as orange and grapefruit, kiwi fruit, mango, papaya, pineapple, strawberries, raspberries, blueberries, cranberries, and watermelon. Sun protection is a must. You should apply a broad-spectrum sunscreen daily. You should take care and avoid any friction or blunt trauma because sometimes small blood vessels can be damaged. You should observe the lesions to see if they increase in size or multiply in number. You should not ignore these symptoms if you develop fever, chills, night sweats, swollen tonsils or glands, bleeding issues, or unexplained weight loss. It would help if you visit a hospital for further evaluation and treatment.
