<s>[INST] My mom had very severe anemia Hg 5.8, She was admitted to the hospital, they did a no.of tests on her and found her ESR results were high, but the immunoglobins test was negative. she had her physical examination of the lymph nodes in her chest and abdomen and they were normal, doctor had seen some swollen lymphs in the xray, could she be suffering from lymphoma. her iron is 2. [/INST] Welcome to Chat Doctor. Severe anemia itself a cause of high ESR. On the basis of swollen lymph node we can not diagnose lymphoma.  Tuberculosis can also cause chronic anemia and high ESR with enlarged lymph nodes. You should not be worry. I suggest you that your mom really need a full work up to confirm diagnosis. You should also mention complete blood count report including peripheral blood film with duration of illness. Thanx for query. </s>
