i had a fusion done on my back 2005. i was in a wheel chair for over two years and i am partly paralized in one of my legs. i was very sick after the surgey and my heart stopped and to this day i am still in constant pain. my advice to every one is do not have any more surgries on back. i have disc diease any many bad problems and i have to walk with a walker and am permently disabled for the rest of my life. please do not have any more eperdirols cause it gives you fibrois of spine. all surgries of back will give you more problems you have to live with the rest of your life. i had 3 back surgries last one through stomach for fusion and i have perment bowel damage. so you have every right to be scared.
