Well another night of no sleep

Its 2.30am and I still cant get a good night sleep, lately I have been waking up or not sleeping at all due to a feeling of tension in my back and shoulders, I think its anxiety but now I am not so sure, its like a feeling of electrcity running through my back and it feels like im stressed, but yet I dont know what Im stressed about or even if it is stress or anxiety. I try everything from going outside a bit, sitting in the loounge or even counting things on the ceiling but yet still here I suffer, I eventually get over it and then do fall asleep but that only happens very late

Also Last night I had a pie, it was still very hot and burnt my palet of my mouth, I thought nothing of it at the time but now it feels swollen and sore so its also keeping me up.
