I need urgent help- this is very serious

Its 3:17am and I have a uncomfortable ache in my back that feels crackable but cant be cracked, google is not helping and worse yet, my bed-sheets are a normal, warm temperature, my pillow is refreshing and cold and my plushies are lined up like a army in formation perfectly, and Im super cozy and its super cold outside my bed. I tried becoming a yoga instructor for a good 20 minutes (turning into a deformed seal with horrible posture) and my favourite general, Scout the velociraptor fell. I refuse to leave mt bed, yet i cant continue living with the ache. Its as hard a decision as choosing which parent to stay with when they divorced (that was easy compared to this) send urgent help before its too late... i dont think i have much time left, it already spreading to my shoulders as i type. This may be my last post, goodbye.
