What can i do if my aunt has excruciating foot pain from diabetes?

Neuropathy: Obviously, she should try to control her blood sugar as closely as possible. Diabetic neuropathy is generally treated with medications such as Gabapentin or pregabalin, sometimes combined with narcotic pain meds. Have her discuss these with her pcp, endocrinologist or podiatrist.

Peripheral neuropath: This sounds like she may have peripheral neuropathy which is a demyelination of the peripheral nerves causing pain. The best treatment is the use of a class of drugs known as the neurotransmitters. Gabapentin or Neurontin or Lyrica (pregabalin) also known as Pregabalin generally gives the very best results. Consult your podiatrist for a rx.

Have it evaluated.: Pain in that area could be due to trauma (fracture, tendon or ligamentous tear, arthritis), infection, inflammation, metabolic conditions (gout) musculoskeletal (bony over growth) or biomechanical abnormality, or neurologic conditions (neuropathy). A thorough history and physical exam and possibly laboratory and radiology exams could determine the cause. Have it evaluated by a professional.
