Hi there ~
I understand your concerns. Augmentin
is an antibiotic that will help clear infection and when the inflammation comes down subsequently, you will experience a feeling of being better with headaches
and congestion. You swollen face indicates that you probably still have some amount of inflammation, which might be as a result of persisting infection or another cause. I wonder if you had an x-ray or your head and neck done, since minor fractures
can delay the healing process as well and present with the symptoms you describe. I hope you consult with a doctor who can help guide you to the specialist if necessary.
Take care and have a lovely day!
