I had suffered acute sinusitis two months ago .in recent 25 days back accidentaly I found two back to back  painless moveable bean seed like swollen lymph node on my scm neck .i visited a ENT he prescribed some antibiotics for 10 days and antidandruff shampoo for a month.now antibiotics course complete for 3 days . initially the size of lymph node is upper one is like bean and lower one is like pea after the antibiotics upper one size is lemon seed and lower one size is rice but it's not completely gone . it's have been a month.i read it in Google if the lymph node stay swollen for 3week or more then it's might be lymphoma... my life is feel like hell now can't focus in anything...am I going to die ?
