Treatment for Diabetes Nerve Pain

Nerve pain caused by diabetes, called diabetic peripheral neuropathy, can be severe, constant, and difficult to treat. It may start as a tingling sensation, followed by numbness and pain. But there are two key points that everyone with diabetes and peripheral neuropathy should know:

  • Controlling your blood sugar levels can help prevent worsening nerve pain and improve your overall health at the same time.
  • Medications can help relieve nerve pain, make you more comfortable, and improve your quality of life.

The single most important factor in preventing neuropathy, slowing its progress once you have it, and relieving many symptoms, is better glucose control, experts say.

Diabetes Care: Managing Your Time When You Have Diabetes

Sometimes, living with diabetes can seem like a full-time job -- trying to keep up with everything you need to do for proper diabetes care.  "Diabetes is a very time-consuming disease to manage well," says Karmeen Kulkarni, MS, RD, CDE, and former president of health care and education for the American Diabetes Association. "The medication, the food, the physical activity -- you add life in general to that whole picture and it ends up being quite challenging."

If you have diabetes and peripheral neuropathy, talk to your doctor about ways to better control your blood sugar, including the possibility you may need to take insulin for better control.

Once you are doing all that you can to keep blood sugar levels under control - including diet, meal planning, exercise, and medication - you should assess with your doctor which pain medication is best to relieve your remaining symptoms.

Fortunately, medications can help relieve nerve pain from peripheral neuropathy so you can function at near-normal levels. You have many pain relief drugs from which to choose. But you may need to try several different types of pain relievers before you find the one that helps you.

Over-the-Counter Pain Relievers for Diabetes Nerve Pain

Some people find relief for mild diabetes nerve pain right on their drug store shelves. Common pain relievers and some topical creams may help, depending on the severity of pain.

Anyone with diabetes should talk to his or her doctor before taking any medication. Even over-the-counter medications can interact with other drugs or cause severe side effects in people with diabetes.

Here are some over-the-counter pain relief options to consider:

NSAIDs (nonsteroidal anti-inflammatory drugs). These medicines reduce inflammation and relieve pain. NSAIDs available without a prescription include aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve).

But NSAIDs can cause harmful side effects such as stomach irritation and bleeding in some people if taken for weeks or months. When taken long-term they can also lead to kidney and liver damage, which may be more likely in people with diabetes.

However, the risk is low.

Acetaminophen. Acetaminophen and other over-the-counter drugs containing acetaminophen relieve diabetes nerve pain without reducing inflammation. These medications do not cause the stomach irritation that NSAIDs do. However, taking more acetaminophen than recommended can lead to liver damage. It is important to read labels and check with your pharmacist.

Capsaicin. Found naturally in chili peppers, capsaicin is found in drug stores under various brand names, including Capzasin-P and Zostrix. 

Capsaicin is thought to ease pain by reducing a chemical called substance P, which is involved in transmitting pain signals through the nerves. On a short-term basis, it is an effective approach. But there are concerns about the long-term consequences. These same nerves play a role in wound healing, and there is concern that capsaicin could prevent wound healing, which is already a big problem if you have diabetes.

Lidocaine. Lidocaine is an anesthetic that numbs the area it has been applied to. It is available in gels and creams, both over the counter and by prescription. Some product names include Topicaine and Xylocaine.

Other topical creams. Salicylate is a chemical similar to aspirin, and is found in pain-relieving creams like Aspercreme and Bengay. Cortisone creams contain corticosteroids, which are potent anti-inflammatory drugs that can help relieve pain. Both are available at drug stores, but there is no clear evidence that they help relieve nerve pain from peripheral neuropathy.
