Pleural thickening is the scar mark of old healed TB pleural effusion
. It does not indicate any active respiratory infection. You need to start chest respiratory physiotherapy
in the form of incentive spirometry in consultation with a physiotherapist. Also If any fresh symptoms develop then you need to visit a pulmonologist for clinical evaluation. The pleural thickening is responsible for chest discomfort
now. Do get a chest sonography and rule out any fluid in pleural cavity
and if its just minimal thickening then no need to worry.
