Are There Any Side Effects Of Cervical Epidural Injection ?

I had a cervical epidural injection this morning and it went wrong, I felt everything! After the injection I was in severe pain the injection site usually near the top of my neck, this one was in my back center between shoulder blades which was strange to me, but during the shot I had broke out in a huge sweat and I had tingling in my chest, back and arms, and a headache was present and now I have this pain on the left side breast area and it hurts to touch the area and can feel pain when I take a huge breath, The pain in my back has subsided but the pain in chest is not gone. My neck pain is better but this pain on the left side breast and back concerns me because I have never experienced this as I have had other cervical epidurals before. Any suggestions?
