I had a botched root canal surgery in January and now have problems with my face. Face pulling/tightness and nasal dryness, no mucus production unless I cry which is alot. Looking for answers, I tested a weak positive ANA(doc said that is sometimes common in women). Had additional tessts an negative for any autoimmune disorder. I have no family members with any AI but I guess that doesnt mean you cant. Anyone else with the same symptoms.
