Had 2nd c7 t1 surgery on the 25th of june. this time the surgeon put a artaficial bone infused with protein to stimulate bone growth. I also have been experiencing Vaso Vagel symptoms on and off since the surgery this is what the nurse said it was. I searched about this protein also called BMPs and there is a lot about the swelling of the soft tissue that it causes and not to use it for cervical fusion. hopfuly that problem is an old one and all the bugs have been fixed, I hope so.
