Hi Doctor.I'm Sruthi. My brother is 26yr old.The previous day he had back pain such that it was difficult for him to sit erect.On consulting a doctor,he was asked to take an ECG,the report of which stated that its normal.But his systolic bp was 140mmHg,and also had total cholesterol level = 284 mg/dl & LDL= 168mg/dl.The back pain subsided the same day,by evening.Now,after 2 days the pain has recurred.Could you please help me by giving a diagnosis of this condition ?
