You need to go to your GP or gynecologist and have them do a pelvic exam. An old tampon can cause problems due to all the bacteria that will collect on it.
And there is also a risk of TSS, or toxic shock syndrome.
you can get something called Toxic....bla bla bla.....and can actually cause death..... you supposed to change tampons every 3 - 4 hours ......
Yes, Toxic shock syndrome was what I was trying to remember the name of. It is dangerous to leave tampons in too long.

So to prevent it - change tampon regularly x
the body has a reaction and rejects anything that shouldnt be there..including tampons.. you would know about it if you did..you would have infection..pain..smell etc.. eg..look what happens if you get a splinter in ye finger..it swells.gets infected and becomes painful till its removed... same thing just like jackie said..change it regularly x
