"I have had a cold for 10 days, I am still congested, I still cough deeply and the secretions are obstructing my breathing a little."

It is important to stay hydrated, rest as much as possible, and consider consulting a doctor if your symptoms have not improved after 10 days. Additionally, it would be wise to seek medical advice if your mucus is green or if you have a fever. In general, cold symptoms usually last 7-10 days, so it is important to monitor your condition closely.
