Good thing you brought her in! Sounds like the infection may not have gone away on it's own. I hope the combo of meds help to make her well soon and that she stops sniffling.
Prayers going out that the xrays next month prove that it is only calcification going on and nothing more serious. You've had a hard enough time already. Only good news should be coming your way for quite some time! At least that's how it should be!!
