shelly, I've been looking at the RA literature for a long time because of my sister. Mayo has one of the best summaries. https://www.mayoclinic.org/diseases-conditions/rheumatoid-arthritis/diagnosis-treatment/drc-20353653#:~:text=People%20with%20rheumatoid%20arthritis%20often,(anti%2DCCP)%20antibodies. So my sister started with the depression, then her feet and hands ached. She likes to say that I diagnosed her, but I just told her that she needed to be tested. She looked on the internet and realized she had all of the symptoms, then went straight to the Rheumatologist and told him--I have rheumatoid arthritis and I want the most aggressive treatment available. He doubted she had RA but called later to say that she had the highest levels of Rheumatoid Factor that he'd ever seen. ( I'm thinking you've had the RF serum test. Do you know your numbers?) He prescribed methotrexate and Humira. She has been taking both for 25 years without having an arthritic flare, but most importantly there is no damage to her bones.
Being premenopausal places you at additional bone risk. It is good you are seeing an endocrinologist.
You might look up the medications on Mayo's medication list.
I'm thinking you are going to have good luck.
