I have been having trouble with my right eye for a while. I used castor oil in it every night for 3 months and that helped. But the right eye seem swollen often in the morning. It also waters often first thing in the morning. I thought it may have something to do with my dog. So I stopped touching her mouth to give her treats. It got better once I stopped that, but then again this morning was swollen. So not sure whats going on with it. But will keep my fingers out of dogs mouth (I figured I would remember to wash my hands.....but clearly didn't every time). And then see how it is in a week or two.
