Since last 2 days I am experiencing fast pulse rates or beats in the vein of my left knee and very rarely in my left shoulder. I am 36 yrs old Male and Hyperlipidemic. I do not have any other pains or breathlessness. My BP checked about a month back was normal.

You have high cholesterol, which is hyperlipidemic, so I don't know how your blood pressure could be normal. What was your blood pressure when it was tested, and are you on medication for high cholesterol?
