Welcome to HCM.
Understanding your concern.
Thanks for your query . The symptoms you mention in query are pointing towards condition called sinusitis (as you mention in query). Further geen mucus is indication of bacterial infection .
I would suggest you to take steam 2-3 times a day to relieve congestion, drink plenty of fluid , give hot compresses to face ,do warm saline gargles and if you are allergic to penicillin then you can opt for amoxicillin
(under expert advice) .
You can also take ibuprofen (if not allergic) or acetaminophen
for pain and swelling. For allergy take over the counter antihistamine drug like benadryl.Consult ENT specialist
(ear, nose ,throat) for proper examination and treatment . Doctor may order blood test
or X-ray. He/ she may prescribe antibiotics course nasal corticosteroids
, antihistamines and decongestant (oxymetazolin).
Hope your concern has been resolved.
Get Well Soon.
