Diabetic Neuropathy
High blood sugar levels can damage the nerves in the feet over time, resulting in numbness, tingling, burning sensations, or sharp pain. This condition is known as diabetic neuropathy, and it often starts in the toes and spreads upward.

Peripheral Artery Disease (PAD)
Diabetes can cause blood vessels to narrow, reducing blood flow to the feet. This lack of circulation can lead to pain, especially during activities, and can slow down the healing of any cuts or sores.

Infections and Ulcers
Reduced sensation in the feet means that injuries or wounds may go unnoticed. If these are not properly treated, they can develop into infections or ulcers, leading to more pain and further complications.
