It's not uncommon for new users to experience some discomfort initially, but this typically self-resolves as you get accustomed to using your iWALK crutch.
In rare instances, the iWALKCrutch can cause localized soreness in the tibial tuberosity, which is the area of the shin directly below the knee. This happens because, for most people, the transition from the knee to the shin (tibia) is fairly straight, but some people have a pronounced bump (see image below). In extreme cases, the size of this bump is more than the standard foam padding on the iWALK crutch can support, which can result in a localized painful “hot spot”.
Fortunately, there’s an easy solution – just augment the existing foam near the front of the leg platform to accommodate the condition. You can purchase a replacement pad from us and simply install it on top of the existing pad, or you can also try some other readily available remedies, such as a folded hand towel, inexpensive gardening knee pads found at home improvement stores, etc.
