I left a tampon in for 3 days when I didn't have my period.
Now I'm experiencing cramps, nausea and lower back pain. Is it TSS?
TSS is really, really, REALLY rare. In the US, it's 1-2/100,000 women. I seriously doubt that you're one of them. I'm sure you just have a cold :-)
Toxic shock syndrome (TSS) is a serious but uncommon bacterial infection. TSS was originally linked to the use of tampons, but it is now also known to be associated with the contraceptive sponge and diaphragm birth control methods. In rare cases, TSS has resulted from wounds or surgery incisions where bacteria have been able to enter the body and cause the infection.
The symptoms of TSS include sudden high fever, a faint feeling, watery diarrhea, headache, and muscle aches.
Hope that helps.
