Did your Dr ever explain the high CRP but low sed rate? I forgot to ask mine and I haven't been to see him since the COVID struck. I'm also on levothyroxine for Hashimoto's. I guess I'll go on methotrexate after we all can get vaccinated for COVID but I am trying CBD and about a teaspoon of TCH tincture alternating every day. I will ask for another sed rate once I'm back in the system. My Dr is part of a large hospital and I haven't wanted to go around there. I am very leery of biologics although my next-door neighbor is on one and seems to feel OK. I may question her further.
Good luck with your kidneys!
