Thank you so much for your reply and the article. My first infusion went very well, and I actually had some not miraculous, but still noticeable, improvement the very next day (even though I wasn't holding out any hope for that, so I don't think it was a placebo effect), e.g. easier getting in and out of bed, in and out of car, up and down from toilet seat. However, 10 days later, backsliding... sadly. (Beginning to realize, after 9 months with PsA that it's a roller coaster.) Due for next infusion this Monday.
I am curious to know what happened about your blotches and swollen tongue after you first infusion? Is that kind of side effect likely to occur in subsequent infusions if you've had none the first time around?
Thanks again for your encouragement, Leanne. Your empathy and kind words actually brought tears to my eyes.
