Summarize the following:
You could also try using a lot of lubricant before reaching for the tampon with your finger. This might make it less painful and easier to do.  Don’t pour water in the vagina or use soap. It can cause infections. And don’t put scented lotions on the vagina; they can irritate the skin. It might also be helpful to use a mirror to investigate what is going on down below. Or you could try peeing into the toilet. The natural process might dislodge the tampon. If that doesn't work though - and this is very important - your next step should not be to introduce a foreign object, like metal tweezers, to your vagina.  It's worth repeating: Do not EVER use another object to get the tampon! That can be very unsanitary, and it could also get stuck. Foreign objects also could scrape the vaginal walls. You want to remove the tampon in a way that doesn't cause you more problems. If you can’t find the tampon or retrieve it, you need to go to the doctor right away. If a tampon is left inside of you, it could cause an infection and be very dangerous. You could also ask a second person to try to get it first (like your partner), but many women are too embarrassed to do that (if you do, the person should wear gloves).  It should be easy for a doctor to remove a stuck tampon. Don’t be embarrassed about this; you should realize that this is something that happens all the time, and the doctor has almost certainly seen it before. You never want to risk your feminine health. The doctor can painlessly remove your tampon in their office. First, they'll likely try pulling it out. If that doesn't work, they can use the same tools they use for an examination to slightly open your vaginal canal and retrieve the tampon. Either way, you won't feel any pain. Sometimes women forget they have a tampon in, and then insert another one, causing the first one to get stuck. Try to remember when you inserted a tampon because leaving one in too long can cause serious infections. If you have symptoms like foul odor, vaginal discharge, dizziness, pelvic pressure or pain, or abdominal discomfort, call your doctor immediately.

Summary:
Try lubricant. Use your fingers only. Call a doctor.
