After good 8 hours of sleep, after wakeup I experience palpitations and chest discomfort followed chest pain. Sometimes pain is like sharp pin pinch pain. Sometimes pain spreading to left arm and neck. I'm experiencing these symptoms from more than 3 months. I consulted cardiologist and undergone all investigations ecg,2d echo,tmt and ct coronary angiography. All are normal. Except my lipid levels I have low hdl levels 26,triglycerides are high 179. Please provide a helpful suggestion to me.
