Although my harsh symptoms were gone afterward, such as tiredness, body ache, and congestion, all of a sudden after the antibiotics I got this harsh cough that was productive with green mucus. The cough was not a dry cough like I had before/during my antibiotics but rather came from my chest and is very loud. I have trouble breathing with this cough. Knowing its been around 40 days and I haven't stopped coughing so much so my back is killing me from the constant coughing, 4 days ago I went to the doctor. He basically told me to cut off sugar from my diet, no junk food, and eat only vegetables and soup for 20 days and I should feel better. (I was a little confused about this suggestion because he never asked about my diet beforehand, previously, I didn't eat junk food every day and I include veggies and fruit in almost every meal. I am quite active and have been consistently healthy.) I was not prescribed anything that can help my mucus but was prescribed cough syrup and an inhaler.I am not sure if a change in diet is a solution and I'm wondering if I should ask for a chest x-ray because I have difficulty breathing.Also this doctor didn't even check my breathing until I had asked him to. He said my lungs sounded fine but did hear mucus in my bronchi.Side note: after finishing my antibiotics I took probiotic pills and drank kombucha, could that have caused this?. ### Response: Generally speaking, eating less sugar and increasing plant-based food is a good thing for your health; but you shouldnt expect this change to make any real difference with an acute infection. I expect in 20 days youre going to feel a lot better regardless of a change in your diet..
