I have two swollen lymph nodes that i've had for years. recently i've had unbearably itchy skin. also anemic. could this be due to lymphoma?

It's possible. : Lymphoma can cause lymph node swelling, itching, and anemia. But so can many other things. Anemia is common in women who are menstruating. Itchy skin is common and can be due to dry skin, allergies, kidney problems or liver problems. And swollen lymph nodes that have not changed for years are not likely to be lymphoma. So you're probably fine, but see a doc to be sure! And try not to worry.
