Perhaps you've also learned the "Notre Dame" technique, a variation of the coffee shuffle to be used when one's hand is too full to grasp the crutch at all. You grip the crutch with your armpit and drag it along, swinging it into position and hoping it's not too crooked when you go to rest your weight on it. It's horrible to watch and quite slow, but sometimes it's the only way.
I understand about the wrist pain. I have some tendonitis in my wrists myself, so I can relate. Try to keep your wrists straight is all I can say, but it's probably more an issue with the squeezing motion.
Since mine is a knee injury, I couldn't have even considered riding a bike. In fact, a stationary bike is one of the torture implements they're now using on me in physical therapy, since my knee doesn't bend right anymore. It seems like too risky of an idea, but ask your doctor maybe. Is your foot in a cast or anything?
The boredom is horrible, as are the feelings of uselessness. I don't know what to tell you. I don't even have a tv. Since I had torn ligaments, bone bruising and hemorrhage in addition to a chipped bone, I have been in a great deal of pain...that means pain pills, hence naps as a form of recreation. I also spent a lot of time on the internet, although one can only sit and stare for so long. I can relate to the "nothing is comfortable" thing - it was even worse for me since I had my whole leg in an immobilizer, meaning that everywhere I went I had this big log sticking out in front of me, and if I sat in a chair for too long the top of it would start cutting off my circulation. I went back to work earlier than I should have, since I was running out of sick days, so that did keep me occupied. Other than that I just tried to get out of the house whenever possible, if only to ride along for a trip to the store, for a change of scenery.
