For a couple of months, I have noticed a pulsating area on my right side of my neck. There is no pain, but you can see it. This is near my collar bone. I am 72 years old. have underactive thyroid and take Levolthyroxin 75g. Have high colesterol, but statins make me weak and my legs hurt. I take co Q 10, fish oil, red yeast rice, and vitamin E.
