What Causes Continuous Headaches With Body Aches And Chills?

I became ill on a Friday with a headache, I am a headache sufferer so didn t think too much of it until later in the evening I started experiencing body aches. I awoke the following morning feelin worse with a continued headache, body aches and chills. I drink a lot of water every day so continued. I was a bit nauseated but never vomited. I did not have diarrhea. I had a low grade temp on Saturday of 100.3. I got a lot of rest. Sunday I felt some better but was tired so took the day very easy. Slept good Sunday night. When I woke on Monday I was doing even better so decided to alternate my day by doing some household chores and rest. It didn t take long and I was not feeling well at all. I took my blood pressure and listened to my heart and it was skipping beats and my blood pressure was low at 93/58, 76/59, 82/56, 91/64. In the evening it was 105/63. On Tuesday it was 100/52, 100/56. This morning it is 99/56. I finally got tired of feeling bad and drank a soda with caffeine. I then felt better. I am experiencing heart palpitations as I write this. When I called the doctor s office they said to stay hydrated and rest. I do stay hydrated and I don t feel this is a problem. I have no chest pain but do have a history of Mild Aortic Insufficiency. I have not had an Echo since 2003 to check this problem. What are your thoughts?
