Vasculitis is commonly referred to as a blood inflammation disease that affects the blood vessels in circulation. The red blood cells carry freshly oxygenated blood from the lungs, pumped by the heart, to all organs and extremities of the body. Inflammation of these healthy vessels can result in blockages, causing circulation to drop. Vasculitis can affect one or multiple organs, depending on the type of inflammation and the intensity of the disease’s progression. Here are the five most common symptoms to look out for early on: 1. Breathing difficulties When vasculitis develops in the lungs, it can cause cavities to manifest in the healthy tissue and affect respiratory function. As a result, one might experience pneumonia-like symptoms, including breathlessness, which worsen with any physical activity. Some people even develop a bloody cough triggered by internal lung bleeding caused primarily by tissue damage. 2. Pain and numbness Vasculitis can also spread and affect the peripheral nerves, causing shooting pains in the body’s extremities connected to the arms and legs. This is often simultaneous with numbness and a sensation of tingling that develop in these regions. Inflammation of the blood vessels will also cause pain under the skin’s surface. 3. Fatigue and weakness Some people also complain of weakness that develops only on one side of the body, along with fatigue that is prevalent with the progression of inflammation in the blood vessels.
