Diabetic peripheral neuropathy is one of the most common causes of nerve pain. It affects many people with diabetes, usually starting in the feet. As well as pain, numbness can lead to foot injuries going unnoticed, which is why foot care is so important. This guide covers symptoms, daily foot care, treatments, supports in Ireland, and whether CBD can help.
What is diabetic neuropathy?
Over time, high blood sugar can damage nerves and the small blood vessels that supply them. Peripheral neuropathy usually starts in the toes and feet and can spread up the legs, and later to the hands. Some people mainly have pain; others mainly numbness, or both.
Symptoms
- Burning, shooting or stabbing pain in the feet, often worse at night.
- Tingling or pins and needles.
- Numbness, or feeling like you are wearing socks when you are not.
- Sensitivity to bedsheets touching your feet.
- Loss of balance.
- Unnoticed cuts, blisters or sores on the feet.
Daily foot care: the most important habit
- Check both feet every day, including between the toes and the soles; use a mirror or ask someone to help.
- Wash feet daily in warm (not hot) water and dry carefully, especially between toes. Test water with your elbow, as numb feet cannot judge temperature.
- Moisturise dry skin, but not between toes.
- Wear well-fitting shoes and seamless socks; check inside shoes for stones before putting them on.
- Never walk barefoot, even at home.
- Do not use hot water bottles or sit too close to heaters.
- Do not cut corns or hard skin yourself; see a podiatrist.
- Report any cut, blister, colour change or swelling to your GP or diabetes team promptly.
Blood sugar and the rest of your health
Keeping blood sugar within your target range slows nerve damage. Stopping smoking, reducing alcohol, keeping blood pressure and cholesterol in check, and staying active also protect nerves and blood vessels. Some diabetes medicines, such as metformin, can lower vitamin B12 over time, and B12 deficiency can worsen neuropathy, so ask your GP about checking it.
Treatments for the pain
Your GP may suggest medicines that calm nerve signals, such as duloxetine, amitriptyline, pregabalin or gabapentin, started at a low dose and adjusted. Capsaicin cream may help localised pain. Ordinary painkillers are often less effective. Pain management approaches, gentle exercise and good sleep routines also help.
Supports in Ireland
- Your GP and practice nurse, including chronic disease management reviews for eligible patients.
- Diabetes services and podiatry through the HSE, especially for people at higher risk of foot problems.
- Diabetes Ireland, which offers education, support and a helpline.
- Annual diabetic foot checks and retina screening (Diabetic RetinaScreen).
Where CBD fits
A small number of studies have looked at cannabinoids for diabetic nerve pain, including topical and THC-containing products, with mixed results. There is no good evidence that CBD supplements treat diabetic neuropathy, and none can claim to. If you try CBD, tell your diabetes team, check for interactions with your medicines, and watch out for CBD gummies, which often contain sugar. Never apply creams to broken skin on the feet. Foot care and blood sugar control remain the priorities.
What the law in Ireland says
CBD oils, capsules and gummies are sold in Ireland as food supplements, overseen by the Food Safety Authority of Ireland. Food supplements are not allowed to claim to prevent, treat or cure any disease, so no CBD supplement can legally be sold as a treatment for diabetic nerve pain. Medicines are regulated separately by the Health Products Regulatory Authority (HPRA), and cannabis-based medicines are available only on prescription in limited circumstances. If a seller tells you their CBD treats diabetic nerve pain, treat that as a warning sign about the business.
If you decide to try CBD
- Speak to your GP or pharmacist first, especially if you take any regular medication. CBD is processed in the liver and can change the levels of some medicines, including blood thinners, some anti-epileptic drugs, some antidepressants and sedatives.
- Keep your proven treatment going. CBD should sit alongside the care your doctor or physiotherapist recommends, never replace it.
- Choose a lab-tested product with an independent certificate of analysis, CBD stated in milligrams and THC not detected.
- Stay within the recommended daily serving on the label, and keep the amount steady for a few weeks rather than changing it daily.
- Keep a simple diary of symptoms, sleep, activity and what you took, so you can judge honestly with your doctor whether anything changed.
- Stop if you notice side effects such as drowsiness, stomach upset or appetite changes.
Choosing a CBD product
Oils give flexible amounts by the drop, capsules and gummies give a fixed amount, and creams or balms are applied to the skin as part of a massage routine. Whichever you choose, check for an independent lab report with a batch number that matches your product, a clear THC result, a full label and a seller with real contact details in Ireland or the EU. Our guide to the best CBD oil in Ireland explains each check, and CBD and pain: what the evidence says covers the wider research.
Safety
- CBD is not recommended during pregnancy or breastfeeding, and CBD food supplements are not for children.
- Do not combine CBD with alcohol, and do not drive if it makes you drowsy.
- Do not apply creams to broken skin or wounds.
- Products containing THC can affect driving and drug tests. Only use products whose lab report shows THC is not detected.
Our position
BDI.ie is run by the team behind two Irish CBD brands, Dr. Hemp Me and CBD Éire. We sell CBD as a food supplement and we do not claim it treats diabetic nerve pain. If you live with diabetic nerve pain, the most useful thing you can do is get a clear diagnosis and a plan from your GP or physiotherapist. If you want to include CBD, do it with their knowledge and with realistic expectations.
Questions to ask your GP or physiotherapist
- What do you think is causing my diabetic nerve pain?
- Do I need any tests, and why or why not?
- What exercises or activities should I do, and what should I avoid for now?
- What pain relief is safe for me, alongside my other medicines?
- Is it safe for me to try CBD with the medicines I take?
- What signs mean I should come back sooner?
A simple four-week diary
Whatever you try for diabetic nerve pain, a short daily note makes it far easier to judge honestly. Each evening, score your diabetic nerve pain from 0 to 10, note your sleep, activity, any medicines or supplements taken and anything unusual about the day. After four weeks, look back with your GP or physiotherapist. Patterns often show up that memory alone would miss.
Exercise with neuropathy
Regular activity helps blood sugar, circulation and mood, and may ease nerve pain. Good options include walking in well-fitting shoes, cycling, swimming and chair-based exercise. If you have reduced feeling in your feet, check them after exercise, choose activities with less pounding, and work on balance with simple exercises such as standing on one leg near a support. Your GP or physiotherapist can advise on what is safe for you.
Small daily habits, especially checking your feet, prevent many of the serious problems linked to neuropathy.
Ask your GP or practice nurse to show you how to examine your feet properly at your next diabetes review.
