hi, last night, i felt a bony thing (Google refers to it as occipital lymph node) behind my right ear just below my hairline. it is about a pea size. it is bony and it is painful when touched. prior to this, i massage my back with pressure since i am feeling back aches. i also carried a heavy swivel chair from the ground floor to my room located in our second floor. i have dandruff, sneezing, my sinuses are aching and even my right ear is aching. i work online with repetitive keyboard and mouse strokes. what could this be?
