My surgeon isn't sure about the extra knot I have on my back. He's going to send me for X-rays and maybe an MRI next week. I just had a fusion of L 3/4 and L 4/5 about 5 weeks ago. I also had a bone graft and bone stimulator implanted. The one knot he said was from where he closed the incision, but I have another knot that's giving me allot of pain from just below where my bra strap would be to the right of my spine. I had a fractured T 12 that I had Kyphoplasty done in January, and he wants to find out if that could be related. If I have to have an MRI at this early stage, I don't know how I could lay on my back.
