Several topical creams can help with nerve pain, but the two with the strongest clinical evidence are lidocaine and capsaicin. Both are available over the counter in lower concentrations and by prescription at higher strengths. Which one works best depends on the type of nerve pain you have, how quickly you need relief, and how much initial discomfort you’re willing to tolerate during treatment.
Lidocaine: Fast-Acting Numbing Relief
Lidocaine is a local anesthetic that blocks pain signals right at the skin’s surface. It’s FDA-approved specifically for postherpetic neuralgia (the lingering nerve pain after shingles) and is the most commonly recommended topical for that condition. You can find it over the counter in 4% creams and patches, or your doctor can prescribe a 5% patch or cream.
Lidocaine works quickly, typically within 30 to 60 minutes of application, and provides relief for as long as the cream or patch stays on. Prescription patches are designed to be worn for up to 12 hours a day, then removed for 12 hours. The downside is that relief stops when the medication wears off. There’s also moderate evidence that lidocaine helps with diabetic peripheral neuropathy, post-surgical nerve pain, and idiopathic neuropathy (nerve pain with no clear cause), according to the American Academy of Pain Medicine.
Side effects are generally mild: skin redness, irritation, or itching at the application site. However, applying lidocaine to large areas of skin or using very high concentrations (especially in compounded formulas) carries a real risk of systemic absorption. Reports to the FDA include cases of serious reactions from high-concentration compounded lidocaine products, including seizures and dangerously low blood pressure. Stick to commercially manufactured products at standard concentrations.
Capsaicin: Slower to Work, Longer-Lasting
Capsaicin, the compound that makes chili peppers hot, works through a completely different mechanism. When applied to skin, it initially activates pain-sensing nerve fibers, causing a burning sensation. With repeated use, those same nerve fibers become desensitized and essentially stop transmitting pain signals. This process involves the actual retraction of the nerve fiber endings in the skin, which is why the effect can last weeks rather than hours.
Low-concentration capsaicin cream (0.025% to 0.075%) is available over the counter and needs to be applied three to four times daily for several weeks before you’ll notice meaningful relief. That initial burning can be intense enough that many people quit before reaching the payoff. If you can push through two to three weeks of consistent use, the burning fades as the nerve fibers desensitize.
A prescription-strength 8% capsaicin patch offers a shortcut. Applied for just 30 to 60 minutes in a clinical setting, a single treatment can provide up to 12 weeks of pain relief for diabetic neuropathy and around 5 months for postherpetic neuralgia. In clinical trials, about 43% of patients with postherpetic neuralgia achieved at least a 30% reduction in pain, and about 24% achieved a 50% or greater reduction. The analgesic effect typically kicks in after about 3 to 4 days. Treatment can be repeated every 90 days if pain returns. Because the patch itself causes significant burning, a clinic will pretreat your skin with a numbing agent before application.
The American Academy of Pain Medicine rates the 8% capsaicin patch as having strong evidence for both diabetic peripheral neuropathy and postherpetic neuralgia, putting it on equal footing with lidocaine as a first-line topical treatment.
Menthol: A Useful Supporting Option
Menthol creams and gels are widely available and inexpensive, and there’s more science behind them for nerve pain than most people realize. Menthol activates cold-sensing receptors called TRPM8, which in healthy tissue simply produce a cooling sensation. In damaged or injured nerves, activating these same receptors appears to reduce both mechanical sensitivity (pain from light touch) and heat sensitivity, two hallmark symptoms of neuropathic pain.
The catch is concentration. At low to moderate levels, menthol provides cooling and mild pain relief. At high concentrations, it can actually increase pain sensitivity by activating a different receptor (TRPA1) that triggers irritation. Products containing 1% to 5% menthol are typical for pain relief. Menthol creams work well as a complement to other treatments rather than a standalone solution for significant nerve pain.
Topical NSAIDs: Limited but Real Benefit
Anti-inflammatory gels like diclofenac are best known for joint and muscle pain, so most people wouldn’t think to try them for nerve pain. There is some evidence they can help with specific types. A clinical trial found that 1.5% topical diclofenac reduced overall pain scores and significantly decreased burning pain in patients with postherpetic neuralgia and complex regional pain syndrome after two weeks of use. It did not, however, improve shooting pain or touch sensitivity, two other common nerve pain symptoms. If burning is your primary complaint, a topical NSAID may be worth trying, but it won’t address the full spectrum of neuropathic symptoms the way lidocaine or capsaicin can.
Compounded Prescription Creams
For nerve pain that doesn’t respond to standard options, some doctors prescribe custom-compounded creams from specialty pharmacies. The most studied combination is amitriptyline (an antidepressant that also blocks pain signals) mixed with ketamine (an anesthetic). A 4% amitriptyline/2% ketamine cream achieved at least 30% pain reduction in 60% of patients with diabetic neuropathy in a phase II trial. In a longer-term study of mixed neuropathic pain, 40% of patients using a 2% amitriptyline/1% ketamine cream achieved 50% or greater pain reduction at 12 months, and 89% rated their satisfaction as moderate or higher.
These creams are not FDA-approved products. They’re mixed to order by compounding pharmacies, which means quality can vary. FDA adverse event reports include cases of serious skin reactions (blistering, chemical burns) and systemic effects (drowsiness, blood pressure drops) from multi-ingredient compounded pain creams, particularly those containing high concentrations of multiple active ingredients. If your doctor recommends a compounded cream, using the lowest effective number of ingredients at standard concentrations is the safest approach.
Choosing the Right Cream for Your Situation
Your best starting point depends on what kind of relief you need:
- For immediate, on-demand relief: Lidocaine cream or patches. Works within an hour, wears off when removed. Good for getting through the day or sleeping through the night.
- For longer-lasting background relief: Capsaicin, either OTC cream used consistently for weeks or a single prescription 8% patch treatment that lasts months.
- For burning-type nerve pain specifically: Topical diclofenac may help as an add-on.
- For nerve pain that hasn’t responded to OTC options: Compounded creams or prescription-strength capsaicin patches through a pain specialist.
Many people with chronic nerve pain end up using more than one approach. Lidocaine for quick relief on bad days and capsaicin for ongoing management is a common and reasonable combination, since they work through entirely different mechanisms and don’t interfere with each other.
