Tampon pain

So, I was in my grandma's car yesterday I the back seat, right? I dropped something and bent down to pick it up and ohh that tampon hurt. Yes I was wearing it correctly, it was ether a Playtex sport regular or a u by Kotex sleek regular, I forgot which. Is that something that is supposed to happen? It feels like I was squishing it and for some reason really hurt. I've never had any pain with tampons so I was wondering if it was normal. Thanks ^^
