well i am pretty self aware and two days ago i noticed a kidney bean shaped soft bump directly behind my left ear. it took less than a day to go from nothing to bean sized. it is soft for the most part, if i feel near the top of it, it feels kinda hard, like a layer under the puss maybe. i can move it a little, definetly feels like it is filled with puss. i have in the past had a bump appear, only to shrink and harden and eventualy i will forget about it, i had one on my upper eyelid. back to the ear bump, physicaly i feel fine, the bump feels a little warm when i mess with it. i have recently used a foaming earwax remover, i dont know if that matters. i do not have insurance, so if it is serious it will have to get really bad before i see a doctor, so i will let it be for a while at least a few weeks, it has been only two days since it appeared. the top of the bump is just on top of the bottom of my skull, from there it extends to almost my jaw, directly behind my earlobe. im thinking it is an abscess or a swollen lymph node, but i dont feel sick. it is a little reddish, maybe from touching it. i just want to know what it more than likely is. thanks.
