Thank you for all the tips. I've got her on Vit C and D2/K3 plus the Natto. Got NAC and Quercetin right here. But there's some stubbornness from working in the medical field for decades. The node was biopsied, I forgot to mention, still waiting on results. Looking for an independent lab to do some blood work to specifically look for signs of clotting and inflammation. Again, thanks for your input and your good wishes.
