I also found this just by doing a google search.
Vasculitis is a group of rare conditions characterized by inflammation of the blood vessels. This inflammation can cause blood vessel walls to thicken, narrow, or weaken, restricting blood flow and potentially damaging vital organs and tissues. It occurs when the body’s immune system mistakenly attacks healthy blood vessels, treating them as foreign invaders.
The condition can affect any size or type of blood vessel—arteries, veins, or capillaries—and can involve any part of the body, including the skin, kidneys, lungs, nerves, heart, and brain. Symptoms vary widely depending on which vessels and organs are affected, but common signs include fever, fatigue, weight loss, rash (such as purpura or petechiae), joint pain, and organ-specific issues like abdominal pain, vision changes, or breathing difficulties.
There are nearly 20 distinct types of vasculitis, each with different causes and patterns. Some are linked to infections (e.g., hepatitis B/C), medications, autoimmune diseases (like lupus or rheumatoid arthritis), or cancers. Others occur without a known trigger.
