Hopefully this is the final update. The sound of the blood flowing through my ear returned right after the so called final visit, and I went again and spoke with a different doctor. He basically told me to live with it since people have that problem frequently. But the next Monday morning I received a call from him very early in the morning informing me he had been thinking about my problem and asked if I might want a CT scan to insure there was nothing left inside. Obviously, I want to find that out, so last week I had it done.
They injected a drug called Optiray 300 into me to enhance the scan which makes you feel like you are on fire. It is an odd feeling. Anyway, the sound had diminished by then and now is completely gone. This morning was my final visit for him to read the scans, but not before I looked them over closely myself. I came to the conclusion there was nothing left in my ear, and both my doctor and the reader of the images both agree.
Here is one of the scans. The arrow points to the dark open area behind the drum where something would have shown up if it was in there.
