Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain swelling of the face on the left side along with inflamed appearance and having a history of
sinusitis and allergies can be due to the reactivation of the infection into the sinus or can be due to allergies while can also be due to dental related causes like deep
tooth infection leading to
dental abscess formation..
It can also be due to inflamed gum flap over wisdom tooth if she has a partially erupted wisdom tooth..
It needs a proper evaluation and investigations like PNS view x ray of
sinuses, dental x rays if she has an infected tooth etc..
Once the diagnosis is confirmed, treatment can done accordingly..
As of now you can give her
Ibuprofen to reduce inflammation and pain and do cool compresses over the cheeks to reduce inflammation and swelling..
Hope this information helps..
Thanks and regards.
