Ice or heat therapy as well as capsaicin cream and even topical lidocaine are what stops nerve pain immediately or near instantly.
Although when it comes to stopping nerve pain, there's no single method that stops the nerve pain immediately for everyone.
You can also take over the counter painkillers like acetaminophen or ibuprofen to stop nerve pain, although they rarely will provide immediate relief for nerve pain because they don't target the damaged nerve pathways, but they can still help.
When using ice or heat packs for nerve pain, apply the ice or heat packs to the area affected by nerve pain for 15 minutes to 20 minutes.
The ice reduces sharp swelling or acute inflammation, while the heat relaxes tight muscles that press on a nerve.
Capsaicin cream, which is made from chili peppers, temporarily desensitizes local pain fibers, although it can cause a warm burning sensation at first.
And lidocaine patches or creams can be applied directly to the painful spot that the nerve pain is occurring to numb the skin and quiet the local nerve signals within minutes.
For rapid relieve of nerve pain, doctors can also give you nerve blocks, through local anesthetic injections that stop the pain signals causing the nerve pain and stops the nerve pain immediately at the nerve source.
Doctors also often prescribe oral medications to stop nerve pain.
The oral medications that are often prescribed to stop nerve pain include gabapentin, pregabalin or even certain antidepressants that calm overactive nerves, but they often take days or weeks to reach full effectiveness, instead of working instantly to stop the nerve pain.
