This is my first time posting. I was diagnosed with PSA 3 years ago. My initial diagnosis was UCTD but it has progressed to the PSA as well. I am on plaquenil, Otezla, and leflunomide but they do not seem to be working very well anymore and my rheumatologist wants to switch me to a biologic. She mentioned either Humira,or Cosentyx. I am so scared to do this and have been putting it off for a year and a half. Any advice from someone who has taken these? Thanks everyone!
