Few weeks back i was hearing my hear beat sound in my left ear and it felt blocked. I tried few allergy medications and nasal drops, it was gone and came back. Currently every morning i feel there is something in my left ear (like water) and i hear heart beat noise for a minute or so and after that its gone i dont hear it. I am concerned about it. I had just ear checkup done they said everything is ok and blood check done, it came out that I have high cholesterol, triglycerides, LDL and Chol/HDL ratio
