Hi and thanks for the query,
For the blocked nose and blocked ears you can take decongestant nose drops like otrivin
Instill 3 drops in both the nostrils 3 times a day for 5 days.
Read the instructions on the crimp to instill the drops.
10 minutes after instilling the drops do steam inhalation.
For the sore throat
you can take any over the counter pain killers.
You may also require an antibiotic, so please see an ENT specialist
for the prescription.
Drink plenty of fluids, do warm salt water gargling 4 times daily and avoid cold
foods and air conditioning.
