Drew,
You need to see a CRS!!! and the sooner the better.
If you are correct and you do have a fissure, you need the proper medication to start treating it asap and before it gets any worse, because that's when it gets much more difficult to manage and longer to recover.
Please trust us - we've all been there!.........
Strange - I would set up your own thread in the "New to the Forum" part - your post is much more likely to be viewed better and more receptive to responses of people offering you help :)
