Pfunk - Your crash story and injury report are scary! I too am VERY glad you weren't seriously injured. They say the longer we ride, its more likely we'll experience a crash. Kinda worries me, but guess its the same for driving, eh?
Again - I'm REALLY glad you had a good helmet on. Do what your doctors and knowledgable buddies here say. Hope you heal up quickly with no residual issues.

Gentle fellow-cyclingTEr hugs to you
Susan
