See answer. It's likely that you have a viral gastroenteritis. Toxic shock syndrome from use of tampons is rare and the patient is critically ill at onset with high fever of 102 or more and hypotension(shock). But without the opportunity to examen you it's best to consult your physician for a definitive diagnosis and treatment.
Retain tampon. hello~ I think you had better go and see a doc so he can examine you to see now serious this is. Retained tampons can on occasion cause very serious abdominal pathology and I think you go and see someone asap to ensure nothing bad is going on here thanks.
