HI, thanks for using healthcare magic
Sore throat is normally related to viral illness thought bacterial infection can occur.
A bacterial infection is more likely if there is a
high fever (greater than 38), pus on the tonsils, cervical lymph nodes.
A viral infection would also be associated with joint or muscle aches pains.
You can consider the use of
paracetamol to help with the pain. There are also gargles or other solutions available that can help with the sore throat examples are chlorseptic,dispirin,
betadine gargle.
An antihistamine and decongestant combination may help with the
drainage.
It can take up to 2 weeks for a viral illness to resolve completely.
If there is no improvement or worsening then you should consider visiting a doctor in your present area.
I hope this helps
