For two years I have had a large hard lump, not painful behind my left ear. I ignored it thinking it was just natural and maybe it was the bone, however over time it got bigger and now there is a pea shaped lump that is very painful under it, and this month I had realised there's another pea shaped painful lump behind my other ear which is causing ear ache, I have become really tierd, stressed and down. Im not sure if I should go to a doctor or not, does anyone have any clue what this could be? Im only 19 years of age, male, Im slim etc.

There are many things it could be, but it is a good idea to go and see your doctor. Speculating and getting scared over things it could be will only get depressing. The doctor will be able to check shape, symmetry, color, and even take a biopsy if needed to tell you what it is. The best option is for you is to go see the doc. If it hasn't gone away in two years and it is now getting sore it's best to go sooner than later. Getting a diagnosis off the internet can often be false. I hope you go talk to your doctor and the best of luck to you.
