Hi.
Welcome to HEALTHCARE MAGIC.
I have gone through your query and can understand your concerns..
As per your complain in case if your friend had upper
respiratory tract infection and he visited you during the active course of infection there is a possibility that you have got exposed to the virus particles leading to upper respiratory tract infection and the stuffy nose or congestion and cough can be due to it..
Although these symptoms can be seen in case of
swine flu also but chances are more towards upper respiratory tract infection and not swine flu..
I would suggest you to consult an Otolaryngologist and get evaluated and a clinical evaluation and blood investigation can be diagnostic..
As of now you can take decongestants like
Phenylephrine orally and nasal decongestant sprays containing
Xylometazoline..
You can also do warm saline gargles and steam inhalations..
Avoid chilled foods..
Take
Tylenol for generalized body aches..
Hope this information helps..
Thanks and regards.
