I had L5-S1 fusion in 2013 and hardware removal in 2014. I have had low back pain when bending and tailbone pain since. It hss only gotten worse. My tailbone pain is so excruciating that I cannot sit longer than 15 min. I have had injections with no help. I finally told my pain dr we need to do some test to see WHY my tailbone especially hurts so bad. I got an xray and it showed 2 screws still there and right above where my tailbone descends and right where my low back pain is. I can push that spot on my scar and it hurts. My question..i have googled and cant find anything...is WHY do i have any screws after hardware removal? I was lead to believe he took them all out years ago. To me this explains all my pain, possibly even the horrific sharp pain that shoots through my rectum for years noone can explain. My pain dr was as surprised as me. He thought all hardware was removed. My spine doctor moved years ago. Do you know why screws would be left in??
