<human>: My doctor has informed me I have a lung function of 62% post a whooping cough infection.I am a smoker.I am attempting to quit but am concerned about the constant lower lobe lung pain.I have no other overt signs of COPD.What is causing the pain? It is at a level where I pain relief is indicated.
<bot>: Hi thanks for contacting Chat Doctor. You gave not mentioned which report you have done.... You had history of whooping cough. For that did you use antibiotic ? You are Also smoker.... So you could have restrictive lung disease. It might be fibrotic disease.... To differentiate restrictive and obstructive disease spirometry done that is pulmonary function test.... Chest x-ray also useful.... According to cause treatment guided... Avoid smoking to prevent damage to lung tissue by elastane that is released by smoking.... Take care...
