I want to welcome you to Neruo Talk. I am sorry to hear of all the problems after your revision of the surgery. I have cervical issues, and two surgeries to correct it too. I know what you have been through. If this is effecting your normal physical ability to sit upright, and are having trouble in your lower area, I would get back to the doctor. The hardware you have inside could accidently move and put pressure on something. You need to have that ruled out. My doctor is always pushing and prodding the hardware I have in my neck, and checking to see if anything negative is happening. Get examined to be on the safe side. These surgeries, especially the more hardware they put in, the more it should be kept track of. This is what I would do, if something didn't feel right. I do wish you all the best. This site should have others, that will help you with ideas. I hope there is a good resolution for you. ginnie
