Sometimes it just really varies -- what can be a mild irritation to one person can be a big deal to another. When the Dr asks detailed questions often things come up that we never would have considered to be part of the equation.
Some Dr's want to take some preventative measures when tests are low or inconclusive, some are more cautious in their approach. It just varies so much that anything we say is just a stab in the dark! Some dx using only bloodwork, some will dx based on symptoms without bloodwork, some require both be present. These auto-immune diseases are impossible to dx based on just one discrete thing...they are much more sneaky!
I would recommend that you don't try to self-diagnosis based on a single blood test. Rheumy's are equipped to understand the test in light of everything else going on with you....everything from weight to amount of stress to how often you get headaches to...who knows? Maybe those achy feet have to do with weak muscles associated with something....it's all a big puzzle - Lupus is known as the disease with a 1000 faces as its so tricky to dx, and the other auto-immune diseases just as tricky.
A slightly elevated ANA can a false positive, or relate to some other kind of inflammation you might have....there are just so many possibilities. Try to stay in the moment and if you don't feel poorly then don't anticipate feeling poorly -- our minds do control some of our physical state!
Hang in there!
