is the liquid still coming? kindly consult a doctor because if you have an infection in sinuses then doctor needs to treat it. I know we all avoid doctors but one must never do a DYI with his own body...
You dont wanna take medicines, fine but at least go to some good doctor, he will get an xray and tell you whether you have an infection.
I have had sinus problem ever since i was a kid and am still living with it ( though never had any pain just block nose etc). These winters my flu also made my ear ache like hell. I couldn't sleep all night but thank God the pain went away the next morning. Still i completed my course of medicines... I still feel sometimes that ear is blocked but its prolly due to my sinuses problem.
