My mum has a cough. It was Chronic before her diagnosis. The doctor said it was psychological. It went away for the first few months of her diagnosis but appeared again. She has terminal metastatic pancreatic cancer. The cough always precedes sickness. However. It only seems to happen when I am leaving the house and she will be alone for a while. Or if I am trying to get her to eat when she doesn’t want to. It almost feels as though she is forcing it. Ct and X-rays have cleared any issues in her lungs. Could it be portable that is a psychological thing and if the coughing were to stop the sickness may also?
