Hello guys, I feel an itch, a crawling sensation, and a burning pain, and cold wet sensation on my upper middle back. Also when I turn my head a certain way, a weird crawling sensation on my shoulder. I also feel pain near my tailbone, or maybe in my tailbone, and down the back of my thigh going to my foot and aching real bad in my big toe. Sometimes if somebody puts their hand on my back gently, it eases the pain a little. But just as quick as their hand is gone, the pain returns. Please help me someone, I'm a little scared. Trying to list all my related symptoms. Most of the time the pain is unbearably excruciating. What is this??
