Rheumy visit - Starting injectable MTX ans Otezla

Just started MTX two weeks ago, just 3 pills half of the dose I would end up with, already having some nausea and a metallic taste in my mouth, so I asked to go on injectables, she agreed. She also gave me a Rx for Otezla, and some sample starter kits. I can’t start them until after the cancer screening, but should be more palatable…
I also mentioned that she read the blood test wrong, and that I was negative to HLA-B27. She said that was good news, because it may mean that I have another form of inflammatory arthritis in my spine and SI joints. We will explore that next visit. I keep telling her, As, but she doesn’t think it is, even with the inflammation and fusing of the ISJ.
Hopefully the radio frequency denervation of the ISJ will help with the pain.
