Hello and Welcome :lol:
Yes, even having family members with lupus does not help you much in understanding how the disease affects you. My daughter's Lupus was completely different from mine and I did not recognize so many of her symptoms.
Knowing your body and how it reacts is one of the best things that you can do (along with learning as much as you can about lupus, its treatments, its medications, and its co-existing diseases). Joining this forum/family is a good start. We are here to help you in any way that we can and we want you to know that, no matter what your symptoms are, you are not alone!.
Peace and Blessings
Look For The Good and Praise It!
