Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns.
As per your complain itchy and
sore throat along with cold like symptoms can be due to
dust allergy while there is also a possibility tat you ave got a viral
throat infection leading to the following symptoms..
You can take anti allergics like Levocetrizine, do warm saline gargles and do steam inhalations..
Avoid spicy and chilled foods and sip on plenty of warm water..
You can also suck throat lozenges and chew
Vitamin C pellets..
You can take anti-inflammatory painkiller like
Advil..
When you are exposed to dust you can cover your nose and mouth with a mask..
In case of recurring symptoms or no improvement consult an Otolaryngologist and get evaluated..
Hope this information helps..
Thanks and regards.
