I'm so happy to know that you will finally be pain free!!
Bear in mind ... when you are decorating your "cage", carefully consider the bells or anything that clinks, just in case you want do anything that your "keepers" don't approve of ... they will know where you are at all times!!
This is the voice of experience here!!
Seriously, I will be praying that all goes well and you will be pain free and mobile in no time at all.
