The nurse told me this sometimes happens but i told her i have never felt this! It took me over 5 min to get out of hospital bed. I explained that i was in more pain after the injection than before! I have taken 1000mg of vicoden in the last 6hrs in 500mg doses. One at noon and the other at 6pm Neither one have provided any relief. My foot feels like a fire is being held to it, but yet is very cold to the touch. And thigh hurts to even move. And they scheduled me for another one next tuesday! But im so afraid whats going to happen, and how long this is going to last! Im a single mom and have to take care of my child, she is very helpful but at only 7yrs old still needs meals and showers. Thanks for letting me vent, it feels so great!
