Throats gets sore to where it really hurts to swallow and then it'll stop and then come back again throughout the day. my nose and ears are very congested. i have no energy i'm super tired but i have no fever. what's wrong with me?

Mono Not A NoNo: While congestion is uncommon, think about Mono (mononucleosis). The rest of what you said sounds like it. Or maybe just a common respiratory virus. A blood test will tell if you have mono, so get to a doctor, because if it is mono you'll need some perspective on this illness as well as some specific instructions. Don't push yourself. Be sure you have a healthy diet and get enough rest.
