Hello girls, could you please tell me something? We've had a cough for four months now, we don't have fever, sometimes there's a tickle in my throat and I can hear wheezing, I don't know what to do, has anyone experienced this before? What helped you? I called the doctor, she prescribed me medication, but I don't see any results. It's been five days since I started doing everything she said.
