Hi and thanks for the query,
Looks like you have an upper respiratory tract
infection- infection of the nose and throat.
Take a pain killer for the sore throat
Try some general measures like.
1) Warm salt water gargling 4 times daily.
2) Plenty of fluids.
3) Steam inhalation will help unclog your nose.
4) Avoid air conditioning and cold
If you do not feel better in the next 3 days then you need to visit the doctor.
Regards, Dr Kishori.
