Hi Jen,
This use to help me some when my feet were on fire.
3 or 4 soluble disprin and sorbelene lotion, disolve the disprin and mix with the sorbelene to a thick paste[ not runny ] then just slap it all over the burning spot after a little while it was asorbed into the skin and hopefully it may ease the burning, [ sorta makes the small nerves a bit drunk

]
It will not take it away completely but it use to at least make it more bearable to handle.
I use to make up enough for the whole day, then when i felt i needed it, i would slap some more on.
good luck
