Good morning Tim - Wow, that was the same hip I got, only I was the lucky recipient of two - and mine failed after only 5 years.

There is good news here in your post - now you know the issue! And -
You don't need to worry about chelation after surgery - over a few months, you liver will process the remaining metal and it will go away as your blood cells are naturally replaced. Mine metal levels were normal 6-7 months after surgery.
If your thyroid is giving you problems, again metal removal and patience are the keys. We were just about to schedule removal of mine after my hips healed, and blood tests showed the levels of thyroid hormones normalizing. We decided to watch & wait and everything calmed down after one year - no surgery required. I still (11 years later) have normal blood tests and just a few nodules that are monitored by ultrasound each year and have not changed.
I also had brain fog, fatigue, headaches, itches & rashes, hair loss and depression - all were resolved within a year after surgery.

Next - I see you are in a rural area, so this may be difficult - you NEED to find a orthopedic surgeon experienced in hip revision, and if possible MoM revision. They are going to find damage that needs repair. And ugly tissue that needs to be excised. I suggest you find a local ortho and ask where they send their "tough" cases. If you are in/near Washington, Seattle has some excellent surgeons who do this work, not sure about other areas. Mayo is possibly an option, if your insurance covers it.

Good luck - will you let me know what you learn from the ortho next week? Finding this issue and dealing with it will put on the road back to good health!
