Your child may have a cold caused by throat inflammation, so you should actively treat it. Don't fight, or you will delay your illness.

Guiding opinions:

You can give your child some amoxicillin capsules (if you are allergic to penicillin, you can change to roxithromycin capsules), paracetamol tablets, and oral liquid for clearing heat and detoxifying. Let children drink plenty of water, have a light diet and don't eat spicy food. If the effect of oral drugs is not good, you can consider infusion therapy. Give some drugs such as ceftriaxone, ribavirin and Qingkailing.
