We have discussed burning before on the forums. You can search for it.

Seems to be caused by irritated or compressed nerves. Mine is correctable by seeing a chiro.

You might also try using an ice pack in the area. 15 mins on, then 15 off, then 15 on.

You might also try the "brugger relief pose" at regular intervals to see if that helps.

That's all I have. Good luck.
