I know from experience that a lot of Lupus patients also have a lot of these other illnesses in this forum (I myself have PCOS, hypothyroidism, etc).
Lupus is an autoimmune disease, your body attacks itself and it can sometimes lead to heart attacks and kidney failures as well as sensitivity to the sun, exhaustion, muscle pain, butterfly rashes, mouth sores, and just pain in general along with other ailments.
The thing with lupus is, that it is an invisible disease. A lot of people do not look sick or even appear disabled, which a lot of people are.
For me, I just thought I had muscle aches when I was traveling with my husband during the winter. The pain got to be excruciating, I couldn't walk.
If there is already a subforum and I am missing it please let me know. I know a lot of support has helped me tremendously.
If there are any lupies in here, a shut out goes to them for trying to lose weight too!
