<s>[INST] My grandmother has this continuous problem for the last 20 years of heaviness in chest due to mucus build up. She always feels like a weight on her chest and constantly forces it out by coughing. She constantly  draws the mucus up her nose to release it from her throat to get some relief. Can you advise what to do. [/INST] thanks for your questioni completely understand your issue.actually in obstructive airway disease or in lower resp tract infection and many other diseases mucosal glands in the bronchus gets hypertrophied or enlarged and so is the secretions from them.these secretions have to drained or expectorated out , if these secretions get retained or not expectorated then these will get secondary infection .if the secretions are yellow u need to give some antibiotics to clear up the infection .you can consult a pulmonologist to prescribe the drugs.to ease the expectoration of secretions steam inhalation should be done to loosen up the secretions .you need to consult a pulmonologist and a physiotherapist.thanks /regardsfeel free to ask more questionsmay god bless you with good health </s>
