Yeah! 4th time is the charm!

You must be so relieved and happy.
I'm so glad you kept at it! It gets so old seeing more doctors but once it pays off....whew!
It's wonderful that this doctor had some new med ideas. I think that is real progress. The terazosin is an alpha blocker and may very well help with both circulation AND pain. Damaged nerves sprout more adrenoceptors. And you never know where you'll be after decreasing the other meds. Opiates cause pain sensitization and some of the others cause swelling. Hopefully, you'll get some side effects relieved without much kickback.
Whatever you decide is right for you, I support your decision. I know you will go into this rationally. And who knows, it may not be forever. Sometimes patients have improvement, get out of their pain and get their implants removed. If you get improvement and can start weightbearing you just might get out of this!
Sending hugs for the day,
