I have R.A, and A.S. I have also started on this journey beging in june and surgery is in december. I have asked lots of question and done research as well and the sleeve is for me. I know it will not cure my issues but any weight I can get off my joints is worth it and if my body is happier that is just a bonus. I get infusions and take daily meds and yes there will be 6 weeks of no diflocinac NSAIDS and my infusuins will have to be delayed a few weeks for my body to heal but to get back things that i have lost is soo worth it!! good luck on your journey!!
