I am male 54 yrs old. I develop chest pain when I walk. It starts after about 5-7 mins and gradually increases upto 22 mins after which I get used to it and then carryon walking for 35-45 mins without difficulty. This is happening for last 5 yrs now. Cardiologist has got tests done, ECG, Echo Cardiogram, Chest X-RAY, CT angio, all are negative. cholesterol is 210-220, Triglycerides 175. Height 5'-9" weight 80-82 kgs. I do not have sound sleep until aided by medicine, I have history of fainting for short time from my childhood even recently about 2 yrs ago. How to get relief of this pain? Is it a case of neurologist or psychiatrist?
