as said earlier go to a pediatric opthamologist. my little girls started out looking "similar" and it was right above the eye in the same spot where your son's is, but at the top not the bottom. We too...had the same thing about the blocked tear duct thing...we thought our daughter had it and took her to the pedi and he was literally baffled. the bump also did the swelling and not swelling thing to when pushed on it. check out my site if you want, it might help you. Go clear to the beginning. Here we found out later that it was two seperate issues...she did have a little bit of "gunk" in her eye but she also had a hemangioma. He's adorable by the way.
