1 Interchangeable needle kits are exactly what they sound like--a set of knitting needle tips, and a set of cords of varying length that can attach and detach from the tips to create many different combinations of needle sizes and cord lengths.
People with diabetes can develop many different foot problems. Even ordinary problems can get worse and lead to serious complications. Foot problems most often happen when there is nerve damage, also called neuropathy. This can cause tingling, pain (burning or stinging), or weakness in the foot. It can also cause loss of feeling in the foot, so you can injure it and not know it.
Over time, diabetes may cause nerve damage, also called diabetic neuropathy, that can cause tingling and pain, and can make you lose feeling in your feet. When you lose feeling in your feet, you may not feel a pebble inside your sock or a blister on your foot, which can lead to cuts and sores. Cuts and sores can become infected. Diabetes also can lower the amount of blood flow in your feet.
