Greetings fine people of the world of Lucid Dreaming!

First time poster here and I've come to share my experience WILD'ing and find out if something similar to this has happened to anyone else.
Lately I've been having extreme difficulties WILD'ing. Here's my story:

I am somewhat experienced in performing WILD. I had about 10 or more successfull lucid dreams using this technique.
In the past it was not very difficult to drift of to a lucid dream. Just lie down, lay still a while and bam - i'm in a lucid dream.
After a while something has gone wrong. Instead of the body performing "checks" to see if my mind is asleep by sending an ocasional itch here and there and an urge to move, my body decided to do slightly more extreme things.
Instead of light itches and urges to move, I started having severe pains (mostly my back, neck or the back of my head). With some effort I managed to overcome these pains and WILD successefully again.

This is where it gets just plain weird...
My body decided to kick it up a notch again. Now instead of light itches or pains, whenever I attempt to WILD it gets unbearable!
I lay in my bed, do everything as usual and right after the hypnagogic stage starts my body suddenly gets warm. After a few seconds it gets hot! Not JUST hot but I get the sensation of burning. My whole body burns and the pain is unbearable, it's like getting set on fire. In addition to the burning pain I start to get nauseous and get an extreme urge to vommit...

Has anyone experienced something like this or has heard anything similar to this madness?
Because of this stragne phenomenon I can't LD anymore
