My husband has two coronary stents in his heart and has been doing wonderfully. (2 and 4 years ago) (One stent was piggybacked on the other because the first one was put in crooked) All other arteries were clear. He said he feels a funny sensation around his heart the past two days; something liken to a numbness, not pain. It s still there faintly, but doesn t get worse or go away. I think he pulled a muscle. does this sound like another blockage? He said it is not pain and no shorteness of breath.
