Thanks for that update:

Here is something to try:

Magnesium lotion applied topically can block pain receptors (called NMDA receptors).

I'll give an example... I fell asleep the other night with my heating pad on my left side for a GI cramp. Normally I follow my past Chiro's advice and only do it for about 15 minutes. But I fell asleep... next day and the day after I had mega pain in my side-- no burn--but deep inside like lightning strikes. I rubbed in a generous amount of Morton Epsom lotion, that I use for other areas, into it, as I was desperate. In 10 minutes all the pain was gone, and has remained so for 2 days now.

This is at most WalMart's locally where I get mine. Also some Walgreen's, and online at Amazon. Use only a little --say a dime's amount on each hand. I'd go for the inner wrist first as I have good response for my carpal tunnel there. Rub into the fingers and a bit on top. If this does not work at least for some of the burning in the first 2 days, then do the elbow areas. If that does not work, then do the neck the next day.

Do you lift heavy weights during the day? Kids, dog food bags?
Do you rest your elbows on tables alot?

If none of this works at all, then the dorsal roots may be damaged. This can happen with viral illnesses, or vaccines.
The dorsal roots lie along the outside of the spine, along the vertebrae, and are way stations for sensory nerves going to the brain. They can get damaged and then send erroneous signals as a result. People vary in their ability to repair them...it is a genetic issue.

But the Morton's is really fantastic for cramping muscles, improving circulation, providing magnesium to the body to use, and blocking those pesky NMDA pain receptors. Many of us here on NeuroTalk use this lotion with great success. It is so inexpensive and lasts a long time. It is really a small miracle.
Not all stores carry it however. That is why I give the short list of those that do here.

Once a day application is all you need of a modest amount.
If it stings going on, then you have some skin problem...it should not sting at all on normal skin. Just rub it in well.
