I find bathing in luke warm/cool water with Epsom salts gives relief for burning and I also have gel-filled cold compresses in the freezer, they are a God send and accompany me to bed many a night.
I am due my fourth Lidocaine Infusion tomorrow and they are fantastic at keeping the pain at bay- they are really uncomfortable day 2-5 and then I get my life back for three weeks before it wears off.

Good luck and stay positive.
