Hi, I'm brand new to forums. I have a question, hoping someone can help with. I give myself Vit B shots in my upper leg without any problem, however, after the last one I gave myself (a month ago) it caused numbness in the area and it is still numb and sometimes causes itchiness or tingling in the area. My dr. has never heard of that happening before. I wonder if any of you have heard of this and what advice you can give to get rid of this problem.
