Knitting vs. Crocheting

[pennylane8.livejournal.com]

I'm recovering from a work-related right hand/arm injury (tendonitis and carpal tunnel).  It's getting much better now, but I had to take a break from most of my crafty passions for a long time, especially anything repetitive, like knitting.

Now that I'm feeling much much better and my injury is coming to an end (yay!), I'm thinking that I can perhaps get back into knitting soon (I have not yet tried crocheting).

Here's my question:  Which is easier on the hands/arms?  Knitting or crocheting?
