TSS PLEASE HELP

I left my tampon in for 10hrs when ur only supposed to leave it in for 8. I took my tampon out about 30mins ago. Felt a touch dizzy a few hours ago and had muscle ache but I was putting the muscle ache down to me going to the gym yesterday. Also this is the first time I’ve done it. I’m super worried. Will I be okay? What do I do? How long do symptoms take to show and what are they?
