I'm seven weeks post op acdf 5-6 and I think I've hurt something. This morning I unthinkingly stretched with my arms up above and kind of behind my head and heard and felt a loud pop right in the front of my neck. It has been hurting and just doesn't feel right since then. Do you think there's a chance that something popped loose or something? I will call my doctor tomorrow if it still feels this way but didn't want to bother anyone today since it's a holiday. Just wondering if any of you have done anything like this?
