I had surgery last year on my back. I had a discectomy done on my L4 Lumbar. Now I have Scarring, Spinal fluid build up, and leaking. I have severe pain in my low back legs, neck, blurred vision, and sever headaches. A lot of times the buttox area feels like it is ripping in different directions. Is this dangerous? Another concern I have, is that when i push the bathroom, whether urinating or the other pushing causes so much pain, that it makes it hard to use the bathroom. I work full time and I feel terrible. I have started feeling really sick to my stomach recently. What can happen? Is this something than can become serious?
