Once you get onto Plaquenil for a few months, the fatgiue, night sweats, and fevers should decrease.
Yes, it's a likely diagnosis for you... but don't tell the Dr what you think it is!!! It's important to share all the symptoms you have, but let the Dr brainstorm -- too often if we mention a diagnosis Drs forget to check out everything and this is how some diseases get missed.
