Not every burning foot is diabetic neuropathy
Assessment reviews diabetes control, medication, vitamin B12, thyroid and kidney health, alcohol, back symptoms, footwear and the distribution of pain or numbness. Examination checks sensation, strength, reflexes, pulses, skin and foot wounds.
EMG/NCS may help in selected large-fibre neuropathy or nerve-compression questions, but it may be normal in isolated small-fibre neuropathy.
Protect the feet and address the cause
- Optimise diabetes and relevant medical contributors with the treating medical team.
- Inspect feet daily and address wounds, pressure areas or infection promptly.
- Review footwear, balance, walking safety and fall risk.
- Use evidence-based neuropathic-pain medication when appropriate.
- Correct vitamin B12 deficiency when confirmed or clinically indicated.
Perineural PRP is an emerging option, not routine first-line care
Small clinical studies have investigated ultrasound-guided perineural PRP for diabetic neuropathic pain, but evidence is not yet sufficient to treat it as a universal standard. A procedure requires a defined nerve target, documented preparation, consent and outcome review.
Methylcobalamin may be used through established medical routes in selected patients, particularly when deficiency is relevant. The exact substance, route and target must be stated before any procedure.
Frequently asked questions
Can diabetic neuropathy be cured by one injection?
No. Diabetes control, foot protection, medical contributors and symptom management remain essential. Emerging injections cannot be guaranteed to reverse neuropathy.
Does EMG/NCS detect every neuropathy?
No. It mainly assesses larger nerve fibres. Small-fibre neuropathy may require a different diagnostic approach.
What is perineural PRP?
PRP prepared from the patient’s blood is placed around a selected nerve under image guidance. Research is emerging and protocols are not yet standardised.
