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.
When diabetics inspect their feet, they should be aware of the following: (1) Color changes in Feet. Paleness or bluishness of the toes and decrease of circulation. Black skin is a sign of dead tissue, and redness with streaks is often a sign of infection. (2) Swelling. Abnormal swelling may be the result of poor circulation or swelling.
