i'm not a doctor & i've never used crack but i have used meth so i'm just giving you my opinion. from what your saying you might be having symptoms of a stroke or heart attack & the lower back could be your kidneys so i would see a doctor asap. also idk how crack is made but if it is "cut" you may be allergic to whatever it is cut with. just trying to help
