Heating an area speeds up circulation, which can bring more nutrients to damaged tissues. More heat and added nutrients helps tissues to have more of what they need to start healing. This is because heat dilates blood vessels, increasing blood flow.
Nerve Pain
It's best to use cold when the pain is still sharp and move on to heat once that sharpness has subsided. The heat will increase blood flow and help tissues heal faster.
During recovery, exercise is incredibly important not just to help your muscles regain function, but also to increase blood flow throughout your body. This, in turn, speeds nerve healing. Likewise, inactivity slows progress. You don't want to overdo it, but the more you move your muscles, the better.

Increased nerve conduction – Increased temperature causes some increase in nerve input and can help to lessen the signals from pain nerves while increasing signals from touch nerves.
Hot temperatures can make pain feel worse, and for people with conditions like multiple sclerosis, heat can trigger Uhthoff's phenomenon, which causes worsening nerve pain. Cold temperatures can make joints feel stiffer and more painful, especially for people with arthritis.
For some who suffer from peripheral neuropathy, the heat may alleviate neuropathy symptoms. For others, it may do the opposite. Here are four tips to stay safe while making the most of this season.
Nerve cells can regenerate and grow back at a rate of about an inch a month, but recovery is typically incomplete and slow. This is a complete nerve injury, where the nerve sheath and underlying neurons are severed. If there is an open cut, a neurosurgeon can see the cut nerve ends at surgery and repair this.
One or both may be helpful. Sometimes switching between heat and ice may work the best for you: Put an ice pack, gel pack, or package of frozen vegetables wrapped in a cloth on the sore area every 3 to 4 hours for up to 20 minutes at a time. Put moist heat on the sore area for up to 30 minutes to relieve pain.
Electrical stimulation at a frequency of 20Hz for one hour accelerates the outgrowth of axons across the site of surgical repair of transected nerve stumps to result in accelerated target reinnervation.
Clinical studies have shown that electrical stimulation enhances axon growth during nerve repair and accelerates sensorimotor recovery.
How do I know the nerve is recovering? As your nerve recovers, the area the nerve supplies may feel quite unpleasant and tingly. This may be accompanied by an electric shock sensation at the level of the growing nerve fibres; the location of this sensation should move as the nerve heals and grows.
“We can take a healthy nerve and condition it today with electrical stimulation and then use that nerve a week later in surgery so that nerve is primed and ready for regeneration,” says Webber. Studies have shown the nerves grow back three to five times faster than if the surgery was done without CES.
Just like with cutaneous scars (which also swell as part of the healing process) the time for swelling to decrease is usually longer than a few days or weeks. Another reason why nerves may take a while to recover has to do with the severity and duration of compression.
“Hot baths expand the blood vessels in those areas and allow the healing properties within the blood to be delivered. They relax the muscles, which takes the tension off of them and the nerves that have been injured.”
If soft tissues are the cause of your nerve compression, massage can ease some of that painful pressure off the nerve. Of course, you might not experience total relief from one massage session, especially if you've had the pain for a long time.
In most cases, symptoms will settle in 6-12 weeks as the area heals and the nerve irritation settles down. You may be advised to see a physiotherapist who can perform an assessment, discuss the causes with you and give you exercises that are tailored to your needs.
In many cases, supplementing with vitamin B-12 can reduce the pain associated with neuropathy. More rarely, it can help repair the myelin sheath, depending on the cause of the neuropathy. However, B-12's ability to speed up tissue regeneration and improve nerve function can be helpful for some.
Magnesium is one of the most essential nutrients in the human body. It plays a vital role in nerve regeneration and functional recovery by reducing the inflammation and causing Schwann cell proliferation at the injury site, which increases axonal recovery.
You may need to rest the affected area until it's healed. Nerves recover slowly, and maximal recovery may take many months or several years.
There are thermoreceptors that are located in the dermis, skeletal muscles, liver, and hypothalamus that are activated by different temperatures. These thermoreceptors, which have free nerve endings, include only two types of thermoreceptors that signal innocuous warmth and cooling respectively in our skin.
Certain infections, such as shingles, can sometimes damage the nerves and cause neuropathic pain. Excessive alcohol consumption can also lead to neuropathy. This may be due to the alcohol causing nutritional deficiencies and toxic damage to nerves. Sometimes, certain medications can also cause neuropathic pain.
Consuming high amounts of caffeine can cause blood vessels to temporarily narrow, restricting the blood flow to your extremities. This could lead to increased nerve pain.
