Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain redness and swelling of cheeks along with warm feeling and a history of seasonal allergies can be most probably due to
allergic reaction only that can be due to
Contact dermatitis caused by any skin cosmetic,bug bite, soaps etc..
Food allergies can also be a cause..
As of now you can give her anti allergics like
Benadryl and do cool compresses to relieve the symptoms..
I would suggest you to consult an Allergist and get evaluated..
He can advise allergic tests like RAST TEST,
Patch test, food challenge test etc to confirm the cause of the symptoms and treat accordingly..
Once the cause of allergy is ruled out avoiding exposure to the allergen can relieve the symptoms..
She can also be instilled
Immunotherapy to reduce the frequency and severity of symptoms..
Hope this information helps..
Thanks and regards.
