It's best to see a doctor, let the doctor treat the symptoms, and don't take medicine by yourself. The medicine you are taking is not suitable for your symptoms.

If you don't want to bother the doctor and want to buy your own medicine,

You can go to the drugstore to buy some, Xiaochaihu granules, or Ganmao Qingre granules to make tea, both of which are Chinese patent medicines, both of which have the effect of dispelling cold and clearing heat to treat colds. There are also Ganmaoqing capsules, optional.

You can buy Sanjiu brand Yanyan tablets or Qingyan tablets for sore throat, whichever one will do.

You can also take some western medicine anti-inflammatory tablets, ceftazidime and confusing spiramycin tablets.

I used to use these medicines to treat my cold and sore throat. I'll give you a reference and need symptomatic treatment. You'd better see a doctor.

I wish you a speedy recovery, peace and health.
