👉 Raised infections, also known as petechiae or purpura, are visible, small red or purple spots on the skin that result from bleeding under the surface of the skin. These lesions form when small blood vessels near the skin's surface rupture, leading to bleeding into the tissue. This condition can be caused by various factors, including infections, autoimmune disorders, blood disorders, or as a side effect of certain medications. Infections are particularly common, where pathogens like bacteria, viruses, or fungi trigger an immune response that damages blood vessel walls, causing them to leak. The raised appearance is due to the accumulation of blood in these ruptured vessels, which can be seen and sometimes felt. Identifying the underlying cause is crucial for effective treatment, as addressing the root infection can help prevent further complications and promote healing.
