Okay so when I was younger, say 12 I remmeber going to the doctors for a large lump behind my ear, not like a marble, but it feels like the bone is just raised more than the bone behind my right ear? It does feel fairly firm but you can feel like little dips in whatever it is? She didn't really say it was anything and i just continued to live life... I'm now 18 and have had no change in the size as I am aware? But recently, say the past 6 months I suffered with headaches for about 2 months, daily headaches that were random in location each time and felt quite outside the head and sometimes my eyes and forehead? My doctor diagnosed these as a part of my anxiety... He thinks every symptom i've gone to him about is my bloody anxiety! Anyway the headaches stopped for about a month and now they've come back! Could this be due to a lack of sleep because I've recently started uni and i am surviving on 4-6 hours a night! I have also noticed an increase in tinnitus last night it lasted about an hour! Am i worrying about nothing and are most my symptoms caused by lack of sleep?
