Hi there,
You're doing great on the walking!
Driving can feel like challenge for sure. Some tips, make sure that the seat is at the appropriate height so your knee is comfortable, not overly bent. Your hip and knee should be at roughly the same level.
Make sure there's enough space between the seat and pedals to avoid your knee being too flexed. You may need to move the seat back. A more upright seat position will support your lower back without straining your knee. If you're driving for long periods, stop for breaks to stretch and walk a bit to reduce stiffness.
For sleep -
Pillows help me get comfortable in bed, making it easier to fall asleep. You can experiment with different arrangements to find what works for you. I surrounded myself with them so I could rest a leg, or arm easily enough, whatever felt comfortable. It can evoke the sensation of feeling swaddled and anything that feels soothing may certainly help you drift off. Doing whatever you can to basically "set the scene" for sleep may be worthwhile. I suggest making up the bed with your most comfortable bedding / blankets along with a few extra bed pillows of different degrees of firmness. Try to block out the light if it's daytime. Minimize noise unless you feel listening to calming relaxation music, a fan, or white noise may help lull you to sleep. Make sure the room temperature is not too hot or too cold. Try to disconnect from the devices at least an hour before the targeted nap or bed time, so it's easier to wind down. Limit caffeine throughout the day and consider natural sleep aids such as Valerian, Chamomile or, Magnesium, my personal favorite, which can assist in muscle relaxation and nerves and promote healthy sleep (falling asleep and staying asleep)
Apply ice for a time before bed to reduce swelling and numb the discomfort. Try some relaxation techniques if you feel they may work for you such as deep breathing, prayer or meditation or even some gentle stretching may help relax your body and mind.
An article on Magnesium from our Library -

Most large grocers carry a variety of teas such as Celestial Seasonings - Sleepytime Herb Tea,
Yogi Teas, Bedtime, Bigelow Cozy Chamomile, all of which may help you relax...at least worth a try.
Time will also help, but that takes patience, especially when you're restless and tossing and turning all night.
Wishing you many nights of peaceful sleep soon!
