Left tampon in too long

So I usually never wear tampons but my period was extra heavy so I put a tampon in and also wore a pad just in case. I put the tampon in at like 5 am before work and went to bed that night forgetting it was in me 😭 I didn’t realize u til the next day that it was still in there until it started hurting me. It’s been a day since then and it’s still hurting. Should I be concerned ?
