According to the doctor, I'll be eating dinner and breakfast in the hospital.

Here's the conclusion of the MRI report:

Proximally retracted complete full-thickness tear of the distal biceps tendon, believed to involve both the short and long heads.

In addition, there is probably a partial tear in the of the common extensor tendon at its insertion on the lateral epicondyle, with epicondylitis.

The muscles have retracted towards my shoulder about 3 to 7 cm.

Now you know. And I'll be wearing a half-cast (no foolin'!) for a couple of weeks. On the bottom, or lower-cast, side of my arm.
