First off, congratulations on your achievement. To go from 22 miles to 154 in two days is remarkable, if a little overly ambitious. Given the cause, I can understand why you did it. But you survived and it shows that limitations are often only mental. BTW, what was the farthest in one day?
Your current state (that truck collision feeling) shows why it is helpful to build up to long distances if one doesn't want to pay a big price. The suggestions for recovery offered so far are great. I would do some brisk walking or jogging as well.
All of Mortgaged's suggestions about hand numbness are spot on. I would add that, given the circumstance, your hand numbness is not unexpected. Having previously ridden relatively short distances prior to your epic undertaking, I suspect that as the miles piled up your back and core got more tired and you spent a lot of miles supporting your upper body with your arms and hands.
If you gradually build up the length of your routine rides, I bet you will find that the hand numbness is not an issue. Add 5 miles a week and in a month, your 22 mile rides will be 40 milers. By the middle of summer, metric centuries will be routine.
I think you should also have someone check out how well your bike fits. If your upper body is supported by the pressure of your feet on the pedals, you won't lean forward on your hands. Also, standing and pedaling for a minute or two thoughout any time takes the pressure off your hands (as well as your seat) and helps with blood flow throughout the body.
I'd rather be sitting on my bike thinking about God than sitting in church thinking about my bike ...
