Had 3 discs removed 4 minths ago in neck. Xray this week shows one of the wedges they put in is cracked in 2 places. Doctor left the room quickly, then came back with explanation 10 minutes later. Felt like they were suprised and not sure what to say to me. I am worried they not being honest. Is this going to be ok or do i need to seek another doctor? Has anyone ever heard of these cracking?
