Symptoms of Red Spots on Skin
Red spots on the skin show various symptoms. These may include:
1.Itching
Itching is a common symptom linked to many red spot causes. It can range from mild to severe and might be teamed with a scaly, flaky texture or swelling.
2. Pain
Some red spots can cause pain, notably if they result from an infection, inflammation, or trauma. It’s crucial to check the level of pain experienced and get medical help if it gets worse or doesn’t get better with time.
3. Swelling
Swelling may happen around red spots, particularly if they’re caused by an infection or an insect bite. This can end up in a raised, tender spot on the skin.
4. Crusting or oozing
In some cases, red spots can get crusted or bleed fluid. This is often seen in conditions like impetigo, MRSA infection, or shingles. If you notice crusting or oozing, consult a healthcare professional for the right diagnosis and treatment.
5. Color changes
Red spots on the skin may change color over time, based on how the underlying cause progresses and the person’s skin tone. As the red spots heal or go away, they may darken, fade, or turn purple, gray, or brown.
However, self-diagnosis and treatment should be avoided and a dermatologist should always be consulted for the proper diagnosis and management of your condition.

Tiny red dots on the skin can be due to a variety of reasons. This includes heat rash, infections, insect bites, allergic reactions, autoimmune disorders, vascular conditions, or skin disorders.
Leukemia can cause red spots, known as petechiae, due to small blood vessels bursting under the skin. However, petechiae can also be caused by other reasons. A healthcare professional should look into it.
The seriousness of petechiae depends on its root cause. In some cases, they may be harmless and go away on their own. But in others, they may indicate a deeper medical issue that needs medical attention. It’s important to talk to a healthcare professional if you develop petechiae.
Heat rash (miliaria) is caused by blocked sweat glands and trapped sweat. This leads to small, itchy bumps on the skin. Sun rash results from exposure to the sun. It leads to red, itchy, and irritated skin. While both conditions may cause red spots and itching, they can be distinguished by when they come up and their specific symptoms.
Erythema multiforme is not contagious. It’s an allergic reaction, normally triggered by an infection or a drug. However, the infection that led to erythema multiforme may be contagious. However, not all individuals who get the infection will develop the rash.
