It’s hard to say. It sounds like TSS as you have been affected by signs and symptoms of toxic shock syndrome such as fever, chills, sever body pain, loss of appetite, dehydration, weakness, extreme fatigue and diarrhea. However, I don’t know whether you have some risk factors. Typically, TSS has been associated with:
Having cuts or burns on your skin
Having had recent surgery
Using contraceptive sponges, diaphragms or superabsorbent tampons
Having a viral infection, such as the flu or chickenpox.
