thanks for writing to us ,
i need to ask you if the lump behind your ear /neck/armpit was evaluated . have you undergone an ultrasound
/FNAC( fine needle aspiration cytology ). if not you need to see an ENT specialist
at the earliest and get that evaluated .
meanwhile do you have reccurent fever
, weight loss
, loss of appetite . please do post in your recent blood reports . i would be able to guide you
i hope this helps
