How does one treat a sinus infection causing sinus drainage down the throat that gets into the upper chest area at night? T his infection causes a runny nose and drainage throughout the day. It first appeared about 2 and 1/2 years ago. The surface tissue inside the sinuses are very reactive in the way of causing itchiness that causes sneezing and more runny nose and sinus drainage. The infection has migrated to my tear ducts now as well and often causes a stinging or burning in the openings of the tear ducts. Is there anything that can kill out this infection in my sinuses and tear ducts? A lot of the food that I eat has limited flavor or almost no flavor at all, and my sense of taste has significantly reduced. Also, normal digestion in my stomach is reduced motility in the gut and a reduction in the normal enzymes and the presence of adequate hydrochloric acid to aid in digestion. Do I have a papyloma virus? Or what do you expect is causing this infection and symptoms in my body? And what do you suggest that I do to kill this infection in my body?
