There are two major causes -- viruses and bacteria. Viruses are the far more common cause. These often last 4-7 days. Unfortunately there is no treatment for this. Symptom management is the only way to make yourself feel better. Tylenol for pain and fevers, benadryl for runny nose etc. Talk to your doctor.
The other major cause is bacteria. These require antibiotics. Specifically strep throat is a bacterial cause of throat pain that requires attention.
