This usually does not cause any discomfort,other than an occasional cough, sometimes I don't even cough,just feel uncomfortable in the chest area. Could it be that my lungs are slowly filling up with water? Will this hurt my health? It's also worth noting that I have anxiety that manifests itself through fear of health problems. Could I just be over reacting? Thank you for your answers <3
