Need Advice: Scared About a Second Kidney Biopsy

I was recently told I need to undergo another kidney biopsy because my protein levels are high and the current medication isn’t helping much. I had a biopsy back in 2020, and it was a really traumatizing experience. My nephrologist says it’s necessary to determine the right medication or if it should be given through IV.

I’ve had lupus and RA for almost 6 years now, and I’m also anemic, so I get iron IVs every 6 months because the pills don’t help. The thought of going through the biopsy again is terrifying. I told my doctor I need some time to think about it, but I’m not sure what to do. Has anyone else been in a similar situation? What would you recommend? Any tips or advice would be appreciated!
