If there is 1-2 nodes(medium)in the right armpit that cause enough pain to cause fever ,particularly at night ,also lead to swelling in face & joint pain (may or may not be related),what can this possibly be? There has been a pus(which was sucked out via injection)culture conducted whose report is normal -'no organism detected'. The problem has persisted for 2 years. Pls suggest possible diagnosis,& further course of action. Regards
