Lupus is an incurable, lifelong condition that causes your immune system to attack your own skin, creating a distinctive red rash. I was grateful I didn’t have the more severe form known as systemic lupus, which is linked to joint pain, exhaustion and - thank you, Google - damage to the lungs, heart, kidneys and brain. She misdiagnosed me with the skin condition rosacea and I spent the next 30 years thinking that was the cause. I’m annoyed with myself for not getting the rash checked out again much sooner, thinking of all those summers I wasted with itchy red lumps. There’s no cure for lupus, but there are several different drug treatments available to control the symptoms of systemic lupus, which I have up to a 20 per cent chance of developing.
