Hi, I am going to be 62 next week, overweight female. I have diverticulosis, fibromyalgia, high blood pressure and a heart condition. The doctor is not sure whether to insert a diffibulator or pacemaker or both. At the moment or should I say over the last two weeks, I have had from moderate to severe abdominal pain. Worse after eating and after a bowel movement. I have felt like my head is in a fog at times. Empty feeling, like I m not there and feeling like I have a low grade fever. Sweats will come on sudden even at night, then chills for a while. It is difficult for me to explain what I am feeling yet I know something isn t right. Any ideas.
