Advice please

I have had this plantar wart for 6 years and have tried lots of home remedies, freezing at the doctor. Nothing has helped. I've been debriding more consistently after showers and yesterday after doing think I found the body of it which I haven't seen before. I started to try to cut around it but it's extremely painful. I left it, put some acid on, then duct tape. This morning it looks terrible and is hard to walk on. I feel like I need to pull it out to be able to walk, but I'm scared. What should I do?
