Welcome to the lupus forum, I'm sorry that you had to find us though. I hate to hear that you're having issues with stiff fingers and toes. The positive ANA is worrisome I'm certain. However, since you have no other symptoms of lupus (you must have 4 out of the 11 to have lupus) I wouldn't freak out to much.
People can have a positive ANA from having a cold. My daughter walked around with a positive ANA since she was very young like age 7 or so. She's now almost 21 and hasn't been DX'd with lupus yet. She has a few symptoms but nothing to say yep for sure.
I've had lupus for 26 years now, my symptoms began at age 17. They Dr's mentioned lupus to me at age 22 and it took them 13 years before saying yes I did have it. It took them that long to treat me, and I truly believe it really has made my condition so much worse.
If you've not checked out the Lupus Foundation website you should, it will list the symptoms and you can get a better look at what we have. If you start having any symptoms I'd let your Doctor know and have them refer you to a Rheumy. They are the best Dr's to DX Lupus and they are the best at treating the disease.
I really hope you don't have lupus, and it's just that you have a positive ANA. Try not to worry or freak out to much yet. Let the Dr's run their tests and see what they say. Please stop by anytime if you have any questions or want to post an update on how you're doing.
Wishing you the best and I hope you get a clean bill of health.
