It took me 13 years to get diagnosed because of the prejudice that young, cute women didn't get that sick.
There are some pretty specific immune tests they have now that make diagnosis a little more certain and help them design appropriate treatments. Symptoms, severity, and disease course vary widely from individual to individual, something that's made it difficult to diagnose in the past.
The right medication can help lupies live a reasonably normal life. However, as you know, the disease comes and goes and has a mind of its own. Some weeks you'll be a ball of fire, then all of a sudden you'll feel like a dishrag. Learning to roll with the punches is key.
The average time frame from diagnosis to death from lupus was seven years just a few decades ago. I won't sugar coat the medications, some of them are ugly. However, most lupies can have a normal lifespan now and many can control their symptoms with over the counter medications like Motrin.
