Hello Sir,
First, please know that in the absence of fever, there is no need to worry at this time with COVID-19. If, however, you have been back from travel for less than 14 days, I recommend that you follow the containment guidelines at home.
As for the cough, you would probably need to have your lungs examined by a physician. This is not urgent in my opinion, so we should wait in the current reality of COVID.
In the meantime, continue with your pumps, they are the best for relief.
Drink plenty of water, rest, and if you are able to get the Sinus Rinse™ product, do so. It will help reduce the amount of mucus in your throat (that runs from your nose) and can reduce the cough.
Happy day,
Alexandre Chagnon, pharmacist
