Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain and the recent medical history of 21 weeks of
pregnancy certain medications cannot be advised to you..
As per the presentation it seems to be upper
respiratory tract infection commonly known as
common cold..
You can take a short course of antibiotics like
Amoxicillin, painkillers like Tylenol and do warm saline gargles and steam inhalations..
Take saline
nasal spray as it will help in loosening the mucous and ease in drainage..
You can also sip plenty of warm water throughout the day for relief..
It no improvement in one week, consult an Otolaryngologist and get evaluated..
Hope this information helps..
Thanks and regards.
