You have tender bumps on your neck
Lymph nodes are small bean-shaped structures throughout your body that help fight infection and filter out harmful substances. Normally you can’t see or feel them but when they’re working overtime, as in the case of lupus, they can become visibly swollen and painful to touch. The most common place to feel them is along your neck, down your jaw and behind your ears but they can also swell in your groin, abdomen, armpits, clavicle, and other places.

A red, butterfly-shaped rash over your nose and cheeks that is triggered by sunlight is one of the more unique signs of lupus, Dr. Lee says. At first it may look like you simply have a flushed face from the heat but unlike a heat rash, a lupus rash may linger long after you’ve left the sun. Here are other diseases that show up first on your face.
