I have had a cervical fusion of C5-C7 done on March 19th and have been having intense dizziness with fainting spells. Is this normal? Im just wondering if this is related to the neck issue or is this something different. I have tried to pin point possibilities of what could be triggering these episodes but have come up with nothing. At first I thought it was the pain medications but these spells have happened when they have had plenty of time to have worn off and when I have not taken any meds yet. Then thought maybe due to low blood sugar so I have checked sugar and it is fine. I drink plenty of fluids because I thought I might be dehydrated. Then I thought it might be my neck brace that had my neck extended to far so I had it readjusted so that is not it either. Just not sure what to do and they are scary.
