I had a 4 level ACDF C3-4, C4-5, C5-6 & C6-7 done in Dec 09 using 4 Peek Prevail disk. Lately, like the last month or month and a half I have developed a catch on the left side of my neck. Sometimes I can feel when it is about to do it but then at other times I "catches" me totally off guard. Either way it hurts when it does it and then is sore for a while. I have tried to narrow it down to a certain movement and it seem to be when I go to look slighly up and slightly to the right. Has anyone esle ever had this or does anyone what is causing it and is it something to be concerned about. I wanted to call my surgeon but I know what they always say is to come in and now our insurance has changed so we have to pay a huge deductible first before the insurance pays and we dont have the money. So I wanted to check with you guys first.
