Hi,thank you for posting your quert in Health care magic. Looking at your symptoms,you are suffering from upper respiratory tract infection-initially cough was there but it is relieved now and right now there is only cold. You are suffering these symptoms more during morning as in the morning the atmosphere is cool.When a person breathes cold air, the tissues lining the nose swell as the capillaries dilate, bringing warm blood to heat the cool air and also there is increase in mucus production. You might find relief by taking Antihistaminics(like Cetrizine),Oral Decongestant(like containing Phenylephrine),Nasal Decongestants Drops(like ContainingOxymetazoline) and Saline nasal Spray. Do steam inhalation.Avoid Cold,Oily and very sweet food as they increase the mucus production.Avoid dust and other pollutants.Drink lots of fluids(warm).Hot tea with lemon,honey and ginger will also give you relief. Hope this answers your question.Get well soon.
