I'm gonna go ahead and say this is what I had back in January. Very weird. Flu-like but no sore throat, no congestion of ANY kind. Slight cough and fever. Felt miserable. Kinda like a mild case of the flu and allergies combined. I took flu meds and slept it off over a weekend. If it wasn't this, then I have no idea what it was. Never had anything like it before though.
