I took the Rutuxan treatment back in Dec. and have had my blood tested every 4 weeks the past 4 months. Until now my platelet numbers have increased to 133-thousands, but I just got tested and found my platelets decreased to 33 period❗️I was shocked❗️I thought I was doing so well. I am crushed. In the same week I received good news that my latest CT Scan was clear, too. I know I feel fortunate that I am clear of cancer for now. But, the number for my platelets is so disappointing . Recently, two joints in thumb has been enraged with pain. My thumb has been sore for months , so I'm wondering if I have RA. Can RA bring my platelets down like I have witnessed? If anyone can relate please let me know.
