Hi...about a week ago I noticed the outer side of my right big toe felt a little tingling, then 3 days after that I wore boots (with heels) to a concert and I m not used to wearing heels! Well that night I stood a lot and even had to take off my boots from how bad my feet hurt! I also used cocaine that night (I m a frequent user, I use cocaine every weekend) the next day after removing my boots all 10 toes were tingling and numb! It s been 3 days and feels like the tingling is going down but I can definitely still feel it in my right toes...also in the mornings, as soon as I step on the floor I can feel the tingling sensation on both feet for about 2-3sec then it s gone! Is this from cocaine usage, or from the boots? I should probably mention that I ve had a little ball on my back (very close to my spine) (dime size) and a ball on my head (I can move it around a little) (about a quarter size) for a few years now!!
