<s>[INST] my father aged abt 70 yrs x-ray report says all things are normal in position and lung parenchyma reveals no active parenchymal lesion..he is fine now ,but 4 days before he was suffered from chest pain suddenly..his neck portion is also in a bit pain...doctors have no clue here [/INST] Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about lung related diseases for his chest pain because his chest x-ray is normal. He is 70 years old and at this age, we must rule out heart diseases first for his chest pain. Heart diseases like heart failure, coronary artery disease (CAD) can cause chest pain. So consult cardiologist and get done 1. ECG 2. 2d echo 3. Stress test (trade mill test) 4. Coronary angiography (if required). He may need cardiac supportive Chat Doctor.  Don't worry, he will be alright but first rule out heart diseases in his case. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks. </s>
