I Have Had Influenza A And Pneumonia Since About The

I have had Influenza A and Pneumonia since about the 16th of August.
I am improving daily but have lost some weight and energy levels are low. My legs are also becoming restless. However, my main concern is the cough which continues. It’s tiring and annoying. Cold air in the mornings and evenings exacerbates the coughing too.
So Dr Rynne, how can I get rid of my cough.
