I had a D'cold Total yesterday afternoon for my fever and cold and after a while the fever was gone but since yesterday evening I constantly feel like yawning but I cant, like every minute I have a need to take long breath. I looked it up on the net and it suggests shortness of breath( I also used artificial tears for my dry eye this morning). Today I checked my respiratory rate on a google app and it shows between 19-24. And my heart rate has increased too. I am in a state to travel in train to get home and then see a doctor? Please answer.
