Reaction to Vitamin B injection

17 days ago I apparently experienced an ear stroke so I sought treatment from an ENT specialist. I recovered fully a week later. Part of the treatment the doctor gave me was a Vitamin B injection. I now realize that my body has been rejecting it. The area of the injection is swollen and I can feel a mass under the skin. The pain radiates out from the injection point into the length of my left arm and from the left side of my body to my entire body now. I also feel weakness, dizziness, heavy fatigue, headaches and blurred vision. I did return to the doctor to report this only encounter his denial of any possible reaction to his injection, so I subsequently left without any treatment for this.
