6 weeks post anterior cervical diskectomy with multi level fusion, having pain in right arm again .

Hello, I see that you have a circumstance very similar to mine and was curious how things turned out for you. I am 3 weeks post op from a 4 level ACDF. I woke up this morning with numbness and tingling in both arms & pain in my Right arm again ( just as before the surgery). I haven't had any of these symptoms post-op until this time. I too am an RN and terrified of the fusion not taking; however an unable to find out if this is normal (swelling ) or something to be concerned with. I appreciate any information you might be able to share. Thanks so much, Scared2
