I feel like I am starting to get the flu or strep. I have a sore lump in my throat, slightly painful swallowing, fatigue, and sore lymph nodes in my neck. I am also very hungry, my appetite had increased quite a bit the past several days. I've been eating lots of veggies but some sweets also due to such cravings and hunger. Is this normal or should I be concerned that I'm just gaining weight?
