I have carotid artery blockage in the left side of my neck. I have had a stroke and 2 yrs ago was told that the blockage was 75% blocked. For the last month or so I have been having headaches on that side of my head and my left ear has been bleeding some also. I have had spells that I have passed out also. I also have afib. Could this blockage I have be causing these problems and getting worse?
