I have had EMG and SEP test and they both showed within normal range. Bone scan normal. My MRI of the pelvis showed that the fusion L5 S1 preformed 5 years ago was still good. I had an MRI of the Thoracic spine and was told that I have T7-T8 a large right sided extruded disc. I have seen 2 neurologists and 2 neurosurgeons, my original orthopedic surgeon, been thru rehabilitation, now undergoing pain management. None of my doctors have explanation of the pain in my lower back and left leg weakness. I can walk for a short time without my cane, but eventually the pain gets the better part of me. I use a wheelchair if the walking distance is far. Pain in lower back and left leg weakness starts getting worse when I try to walk very far. I can feel the muscles in my back tighten and I have stop what I am doing and lie down. I spend a majority of the day in bed. I do have good days when the pain is not as severe. On those days I think I need to try to clean up what I can around the house. I then end up in the bed for the next few days in severe pain and the cycle never stops. I have not been able to work since last year. I want my life back. Please give me any suggestions if there are some test that they have not done yet that might show the reason for all my pain!!!
