There is never a good time to be recovering on one foot after a surgery or injury. You've quickly found that crutches don't fit your needs. They are often more painful and limiting that the initial surgery. With them you loose the use of both your hands as you try to balance on one foot.
Someone might have mentioned a knee scooter (also known as a knee walker or roll-about) as a modern option to crutches. They've provided relief for millions of people, just ensure you ask the right questions to make sure you get relief, not more struggles.
This is a medical device that you will rely upon for your safe recovery. Make sure the device is not a disposable toy but a device registered with the FDA as required by law and your insurance company.
