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.
Individuals who have diabetic neuropathy can also experience swelling in the feet and ankles, according to WebMD. This condition can lead to infections, as neuropathy can cause reduced sensation in the feet. People with diabetic neuropathy should do a daily foot inspection to check for blisters or injuries.
