Need answers how to get rid of wart on my elbow !!!!

So I got this wart on my elbow 5+ years ago I’ve tried over the counter stuff, went to the dermatologist, tried duct tape, I’ve tried apple cider vinegar, and I’ve tried crushed up garlic with duct tape over it. So yesterday someone told me to use a razor to remove the callus/ tough skin on top of the wart then apply Apple cider vinegar and then crushed up garlic follows by duct tape. So i did this. This morning i woke io took the duct tape off and there were 2 blisters surround my wart near the bottom of it. I got scared because i thought those were two more warts that formed. Is this just from the acidity from the apply cider vinegar or would i be concerned ? What have you guys done to get rid of a wart on your elbow?! It’s drive me crazy!! I also got a small one on the tip of my pointer finger from picking at that one (i must have had a cut there or something)
