My symptoms - I had a sore throat, coughing up mucus, mild temp, sneezing etc, about 4 months ago, ever since, the symptoms keep recurring, mainly coughing. mild crackles in my airways upon waking, which is cleared by coughing up mucus. I have been to my GP quite a few times, have had three different types of anitbiotics, a chest Xray and lung funciton test. Have also been tested for whooping cough and other types of viruses, which are all negative. I feel unwell a lot, and am really sick of coughing, which makes me tired and irritable. I have been taking Womens' multivitamins and Vitamin D3, calcuim and magnesium. I eat a balanced diet and sleep okay. I don't cough at night. I am 62. Can anyone help?
