Crutches hurt and are hard to walk in. Navigating stairs on crutches is dangerous. Underarms get bruised and rubbed raw. Crutches make your arms and shoulders fatigue. Traditional underarm crutches can be painful, especially if they are not fitted correctly. There are many nerve endings in the armpit, and they get irritated and sore, sometimes even causing shoulder and neck pain.
If you are using crutches for an extended period of time and you are mobile on them quite a bit, your wrists will ache and you can even end up with a serious condition like carpal tunnel. The pads help when exploring how to make crutches more comfortable, but won’t prevent sore hands from crutches.
