I've had a sinus infection for about 4 weeks now. After the second week I thought it had disapeared but i woke up one morning and it hit me like a truck. I feel very worn out, facial pressure, espically right under the eyes and around the nose. Within the past few days, I have not been able to breath out the left side of my nose. It feels plugged up and needing blown, but when I do blow my nose, nothing comes out.
