Red spots on the skin show various symptoms. These may include:
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.
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.
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.
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.
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.
