Hi, good day all. I am 33 male. I am getting cough and mucus (yellow light green) from last 20 days. I am using whey protein from 1 month as i started my gym workouts and i suspect that is causing my problem. I stopped it from last 3 days but cough is still there. Also i used to take raw spinach and raw bracoli which I stopped it already. Cough is increasing while sleeping/lying down. Please shed some light on my problem. Early morning i felt very difficult as my chest catches with full mucus.
