I had a posterior fusion c5/c6 to c6/c7 ( revision for previous acdf non-fusion) and microdecompression at the same levels a few days ago. I woke up with thumb, index and middle finger numbness on both hands, now it's moved to my forearms as well. I didn't have these symptoms before my surgery. Has anyone here experienced this? My doctor is sending me in for a MRI & CT Scan Monday, but this is really worrying me since it just seems to get worse.
