For a few days now I've been heavily injecting meth and yesterday I injected back to back and started feeling weird and the back of my head hurt and not only but nauseas and was shaking very bad . The shakyness and all that went alway but the top corner not temple but a little toward the center front has a little pain . I committed and all the other symptoms went away and I was laying down. And felt like blood in my throat and cough up a little blood what's wromg
