Help! I had acdf surgery June 8th, two new discs at level c4/5 and c5/6. I was has having problems with muscle twitching and called my doctor and thought it was just the Lyrica, my ns is out of town so his partner ordered a ct and mri just to be safe. Today I find out that my donor bone c4/5 is bulging, WHAT the ^&^&(. Has anyone else had this happen???
