Over the past couple of weeks, I've developed numbness and tingling in my legs and feet, accompanied by muscle spasms and electrical shock-type pains in both legs and feet. It's been really bad over the past few days, to the point that my legs have given out on me on several occasions, and I'm having trouble walking. My mid to lower back has been extremely painful as well. Is there anything that can relieve these symptoms in my legs? I've been trying to ignore it, but it's becoming completely disruptive. Initially it would happen just on occasion, but now it's all of the time. There are areas on my feet and legs that are numb to touch.
