#rarediseaseday Hi, don't worry, I'm still posting about books, but this month I'm also doing a challenge throughout February to promote Rare Disease Day. I have Vasculitis, and this is my Smiley Selfie.
"Vasculitis means "inflammation of the blood vessels".
Inflammation is your immune system's natural response to injury or infection. It causes swelling, and can help the body deal with invading germs.
But in vasculitis, for some reason the immune system attacks healthy blood vessels, causing them to become swollen and narrow. This may be triggered by an infection or medication, although often the cause is unknown.
Vasculitis can range from a minor problem that just affects the skin, to a more serious illness that causes problems with organs such as the heart or kidneys."
