I have low back pain with nerves moving into both sides with terrible burning sensation, keeping me from moving. I was given a shot about a month ago that was not given right, blood came back and was all over floor. I am having problems since, cannot comb hair. I was using myour arms before that. I know that Doctors don`the usuallyrics speak against medical m staff but this nurse apparently hit a nerve or a blood vessel. Please tell me what you think.
