@rsroseco Welcome to Mayo Clinic Connect, a place to give and get support.

To have swelling suddenly 2.5 years after surgery and continuation since this is obviously concerning and you are looking for answers and support.

I moved your question to an existing discussion where members like @doodles418 @cobweb @amberpep @contentandwell @debbraw have previously discussed this topic.

A revision is a major surgery, especially since you are unsure of the problem. You said that you met with 2 surgeons. May I ask if either of these surgeons were at a specialty or teaching hospital system? If not, have you considered getting a third opinion from a specialist?
