Sarah, Nik had a vicious sore throat and on and off fevers. His sore throat was so bad they gave him T3 for the pain. He didn't have the fatigue too bad because his mono was mild but you definitely seem to have the symptoms of mono. If the titers were high it can cause mono so be careful. Chronic Fatigue Syndrome is thought to also be associated with EBV but so far the CDC has not found a definite link with each other.
In other words, call your doctor tonight, the GP, neuro, whoever you have to. You can't work in the food areas for sure if it's mono.
