I m having a persistent chest congestion, with productive coughs, but can t seem to shake it. Chest literally rattles and wheezes when I inhale or exhale deeply. No other symptoms whatsoever, just the phlegm. No fatigue, no breathlessness, dizziness, no pain, no headache or nasal congestion, not even a sore throat. Taking good vitamins and supplements, eating right, exercising daily. It s been two weeks now. Any ideas?
