I had a epidural for pain today in my lumbar I have started to feel worse?

I had a epidural for pain today in my lumbar around l5 and right after i had a very short headache it was done at around 10am and slowly i have started to feel worse and worse. I have taken 60mg of oxycodone through the day and its noy touching the pain. My pain is in my upper back n neck now. I first noticed it when i looked down it pulled at my spine like a knife in my lumbar now yhe pain is between my shoulder blades and i just feel off and my anxiety is a the worst ever. What is wrong? Plz help me im freaking out. Do i need to go to hospital. Is it serious. Will it go away? I have a bad neck more than my back but the pain meds help any other time. Thus just is so off feeling. Im in tears literally.
