My father ad a heart attack a week ago and had that procedure where they go through the wrist to unclog artery . He had one two clogged arteries, one 99% which was unclogged and then 90% which he will have to return for. His appetite has been awful not wanting to eat much, but he says he feels bloated all the time and pressure on his chest. He also has been complaining of really bad headaches lately. Blood pressure seems normal 120/74 so what would be causing the bloatiness, and how can he relieve it
