Hello.. Well in this weather you try to avoid cold items,fried food,curds, banana in the night time specially because all these will aggrevate the breathing difficulties...you need to take regular steam inhalation with carvol tablet so that it provides you relief...hydration is also very important..drink ample amount of water...there are tablets like mucinac which will help in resolving the mucus...but first we need to examine you and then see if any of the tablets or antibiotics are required..thank you
