I wouldn't be worried. I had mine out on the 26th also. Maybe he gave you the dissolvable stitches and just needs you to go back for a post-op checkup. As for the swelling, that could last up to 5 days. My oral surgeon said that after the first 24 hours, if you still have swelling, there isn't really much you can do for it besides wait for it to go down on its own. It's been 4 days since I had mine out and I have a little bit of swelling (only noticeable if you know how thin my face was) and I really don't have much discomfort. I hope everything goes well with your healing and if you are still concerned, call the oral surgeon and ask him what he thinks...
