Been having pressure n my face between my nose & eyes runny nose, cough, lightheaded when blowing my nose it's kinda green alil? No fever no aches!

Good old cold! Sounds like you have a good ol' cold. Congestion from the cold gives that pressure feeling, and the drainage can cause the cough. Kinda green means the body is sending white blood cells to fight the infection - that's a good thing. Since no fever or aches, doubt influenza or sinus infection. Wait 10-14 days with symptomatic care (humidifier, saline rinses of sinuses...) and if not better, doctor.
Sinus infection? Check with your doctor to see if you may have a sinus infection, more likely if you had caught a cold within the previous 10 days.
