<s>[INST] Hello Dr, I had high blood pressure 140/94 last week and relatively high heart beat 90 last week. This week ( 2 days back ) i noticed tiny (0.5 cm) red soft movable painless rubbery lump which has not changed in size near my armpit and one below my ear 0.5 cm) . I have lower back pain sometimes for past 2 days, no sweating and fever, urine like smell sometimes ,little body fatigue and dizziness sometimes when i am resting but it reduces while i am doing some heavy physical, no breathing problem, no itching and rashes , stiffness of neck, clear urine and no chest pain. I s it some kind of kidney infection or lymphoma? [/INST] Blood presssure has nothing to do with malignancy.the swellings are very small, <1cms which are not significant. your low back may need pain killers. you also have no other systemic symptoms suggestive of lymphoma. keep a followup of these lymphnodes and see for the increasing size.if increases in size these nodes biopsy should be done. you need to undergo routine urine examination to see for abnormal cells or microorganism followed by urine culture to rule out infection. </s>
