It's been 8 years since I had T-bone and cheekbone surgery. I wanted to remove the titanium screws, so I went to another hospital and tried to open them, but they said surgery was impossible because I had a lot of scar tissue and was covered with bone. It's been so long since I had surgery, I didn't even know I couldn't do it. I want to remove them, what should I do? ㅠ
