I read that the mRNA progresses certain cells and causes nodes to swell but says they should return to normal. It’s been a year and mine haven’t which led to the biopsy. . One person suggests that maybe low grade lymphoma or leukemia was already present. It’s just hard to know for sure but I know I had no swollen nodes prior to getting the two shots and booster. I am scheduled to see hematology tomorrow and praying that the nodes are just reactive as the doctor told me. If they’re reactive how long before they return to normal. At the initial they were very swollen and hurt but the soreness subsided and they’re still present. Ultrasound showed them to be increased in number with two getting larger. As one doctor put it, the vaccines though tested still have unknown reactions.
