I don't know for sure if it is flare related or not, but my eyes often tear like that. I remember when I was a kid having that happen around the time I first started experiencing symptoms of SLE. I, my brother, and some other children had earned money doing yardwork.......they all bought toys, I bought a pair of sunglasses
I have sunglasses stashed all over my vehicles, my house, my purse etc..
I hope your flare ends quickly and you are hive-less and feeling better soon!
