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.
Dry and itchy skin in diabetics is primarily caused by high blood sugar. The body pulls moisture from tissues to try to counteract the increase in glucose levels, and can leave the skin dry and irritated. Other causes of itching are caused by fungal or yeast infections, diabetic neuropathy and poor circulation. Nerve damage can reduce the body's ability to sweat, drying out the skin. Poor circulation, neuropathy and infections can cause numerous problems in the extremities of diabetics, especially the feet.
