Ok, like Joy said, take a deep breath. Worrying about
what the ANA might mean isn't going to make things any better (or worse, for that matter.) Giving yourself an anxiety attack will only make things worse.
ANA isn't a reflection of inflammation, so a steroid shot for inflammation isn't going to change the ANA reading. ANA is a very general indicator, so reading up online about
what it might be will only bring in information about
all kinds of things that it probably is not, and worry you even more.
If your organs were involved you would be feeling VERY SICK. From what you've said your diagnoses of mild scoliosis and costochondritis match the symptoms fairly well.
You might call your rheumatologist and ask to be put on the cancellation list so that if someone cancels you can be seen more quickly. Other than that, just be gentle with yourself, try to get deep restorative sleep, mild exercise, and avoid junk foods.
