People have always said about me and others that we have a screw loose. I don't know about others but for me it has been confirmed. Back in 2011 (I think the year is right) I had a pump malfunction (for those who don't understand a heart attack). This was my 3rd little problem and since I already had 7 stints I was told I was what they called a full metal jacket. This pipe was full. This time they did a double by pass. Most of the time when they do this they use wire (safety wire I hope) but in my case they used metal plates and screws. 3 weeks after the re-plumbing one of the screws came loose and turned sideways. They went back in and removed it. Now this has happened again. Hence a screw loose. I'm trying to find a doc. that will just deaden the skin area around the screw and simply cut the skin and pop the screw out. Wish me luck.
