Hi doc, I recently had my health check up and everything looks normal but under chest xray doc showed me something old infection and suggested me to check with chest specialist. I am having little chest pain and would like to know if this is related to the old infection mentioned in my report. Report says : Couple of thick walled small size cystic/bronchiecticatic lesions noted at left hilar region. Thickened right C-P angle...S/O MILD PLEURAL thickening F/S/O old infective etiology.
