Hi,thank you for posting your query on health care magic.
Looking at your symptoms like cold not getting relieved in 2 weeks,
yellow sputum,fever,etc,there is a possibility of bacterial infection causing inflammation of the nose ,throat and
respiratory tract.
You may find relief by taking the following medications:
Oral Antibiotic like Amoxycillin with
Clavulanic acid combination,
Oral decongestant like
Phenylephrine and Nasal decongestant drops like Xylometazoline(take decongestant only if you are not suffering from
hypertension),
Antihistaminic like Cetrizine,
Mucolytic like Ambroxol
Antipyretic like Paracetamol,
Analgesic with Antiinflammatory like Ibuprofen with Antacid like Rantac.
Also do steam inhalation.Do warm saline gargles.Drink lots of warm fluids.Avoid cold food and dust.
After following the above measures,if your symptoms are not improving in 2-3days,then it would be advisable to consult an Otolaryngologist doctor.
Hope this answers your question.Take care.
