Hi Vanna. I am sorry I did not read this till now. Your problem is a PAIN SPECIALIST problem.If you are still in pain go to the ER as soon as you can. That's what my Pain Doc says.I have to get the shots myself.Lower Lumbar area in my back, both knees, and shoulder.After the shot..you can expect maybe a little discomfort..but not your kind of pain. Please let us know how you are doing!
