Monday I Had An Epidural In My Neck I Started

Monday I had an epidural in my neck I started feeling sick that same day and became progressively sicker. I could feel fluid in my right ear and chills that run down my arms and legs. I am feeling slightly better but still feel zapped of energy and still getting the chills, tingling, numbness. Called the doctor but he said it was just a coincidence and probably the flu. What do you think?
