Oh the pain

I have been having such bad cramping and pain in my lower back since I received my shot on Monday. It is bad enough that even vicodin is not taking the pain away. I don't know if this is normal but I suppose I will call my doctor in the morning. On top of that I am also getting a cold and or ear infection. At least the pain pill took away my ear pain for now. I just want to be healthy. Is that too much to ask?
