I'm sorry about your pain and trauma. Unfortunately, since you were drunk, you may have experienced additional trauma of which you are now unaware. I would check with your doctor for a pelvic exam to be sure there are no injuries. You will likely heal on your own but it would be best to have it checked out.
As for the tampon - you should be concerned if you ever forget about one because it does increase your risk for infection. Be especially alert to fever, chills, body aches and go to a doctor right away if this happens. But it sounds like this is not the case for you so having your doctor check you is the best idea, coupled with patience as your body heals.
