For the last few days my right eye has been red and intermittently itchy and dry. I have been waking up with more crusties in that eye than usual, and they have a greenish tint. Yesterday I woke up with a sore throat and my body became stiff and achy during the afternoon. This morning I hacked up some phlegm with blood in it. Everything I hack up or blow our has a greenish tint. There is some discomfort behind my eye and my nose, and my lymph nodes may be swollen, but I do not have a headache or a fever. I thought it may have been allergies the first day, but I took some echinacea yesterday and my symptoms didn't worsen. I'm thinking I may have a sinus infection, I live in a very dry climate so that may be the cause.
