Hello. I have been feeling numbness and tingling on the left side of my face, left hand, and feet. It travels to other places too. I have researched so many things but I just came across a site that said the depo provera shot could cause vitamin b-12 deficiency. And vitamin b-12 deficiency would cause all of my symptoms. And also these symptoms started after I got the shot. Anyone have any information on this? I have only had one shot and other than this I have been fine.
