Does lidocaine help nerve pain?

According to my neurologist, lidocaine works by blocking sodium channels in the nerve endings, which reduces pain signals. It is quite effective for localized neuropathic pain like post-shingles neuralgia. However, he warned me that it is only for symptomatic relief and won't cure the damaged nerve.

Yes, lidocaine patches or creams help dull the sharp, burning sensation of nerve pain quite well. Just make sure not to apply it on broken skin or open wounds.

I totally get it, nerve pain is absolutely exhausting and it is so hard to find anything that gives peace. Lidocaine can give you that temporary breathing space by numbing the sharp shooting sensations. I really hope you find some relief soon, please take care.

When my mother had severe nerve pain, the specialists at Manipal Hospital suggested lidocaine gel as part of her treatment. They clearly told us not to self-medicate with it because nerve pain requires proper prescription meds. Please consult your doctor before buying any over-the-counter patches.
