Hello and Welcome to our family;
As we are not doctors, we cannot tell you if your symptoms are truly Lupus or not. However, your symptoms are consistent with those suffered by persons with auto-immune disorders (of which there are over 60 possibilities and Lupus is included in those). It is possible for a person to have Lupus with a negative ANA, but it is also possible that you may have another AI issue.
You might want to read through the stickys at the top of each forum here at WHL, they are filled with information that may answer some of your questions. They will also provide you with a lot of information about Lupus and other AI diseases. Arming yourself with information will be helpful the next time that you see your doctors so that YOU can tell them what tests you'd like them to run in order to determine exactly what is causing your problems. We must learn to take control of our health care and not be afraid to demand things (action, tests, answers, treatment, etc.) from our doctors. Often, we have had to educate our doctors about our disease in order for them to provide us with appropriate care and treatment.
We are here to help you do this and to help you find a way to manage your symptoms and learn how to make the best of your life with your illness. You are not alone! I wish you the very best.
Peace and Blessings
Look For The Good and Praise It!
