So sorry to hear about your diagnosis. I think it is hard to tell sometimes, and maybe it’s both! Fatigue is a big one for me. It’s much better than when I was first diagnosed, but it is still there. I had shortness of breath at the beginning, but it is also better. My IgM was 5489 at diagnosis, and I had hyperviscosity which caused two eye strokes. Am now at 1460. Again, much better, but I still tire out and every now and then, do have shortness of breath. Wish you the best in your journey. At least it’s an indolent cancer, so that brings me some peace of mind.
