OK, Im 17 and scared I have a brain tumour. I had anorexia last year which exacerbated my anxiety. I had it on and off though since I was 5 and my dad left (the panics), but I have hypoglycemia and it made it alot worse. I have since recovered- my hormones are still out of whack- but it was never incredibly severe. I eat a healthy, largely clean diet and practice yoga and cardio. In april, the day after a dentists appointment, I began getting a pain in my jaw. He had filled a natural crack in the side of 2 of my molars ( one on each side) which he said may trap food. The pain was in one of these it felt, below the jaw. The pain niggled away on and off but after noticing the tiny bit he had filled had fallen out on that tooth I went to the dentist. He took a look and said my teeth were fine- I had the tiniest but not bothersome bit of decay on that tooth- and my wisdom teeth were coming in. In August I felt some pain across my upper rib and sternum area - aches and pin pricks, worstened after doing planks and floor work- which I worried alot about. they eased and then odd niggles would return on and off. Last week I went swimming and later the day had a bout of nausea. I have since then had pains in my neck, odd stabby aches at random times. I do have bad acid reflux though.My neck has felt stiff and my jaw joint stiff and ears a little pressured. I have been extremely tense and anxious and convinced Im dying, for 2 weeks on my laptop each day looking up what may be wrong. Maybe this is what has caused my eyes to feel stiff and tired. Also when I've been laying down and putting pressure on the back of my neck sometimes I get an odd tingle in my forehead. I went to a great doctor today who listened to my heart, felt my neck, took my BP and pulse and said everything was perfect- my nodes werent swollen etc. She told me it was all muscular. After getting home I realised I forgot to mention the tingle and some pains in my head on and off. I told her I was scared it was 'a tumor' but didnt say 'brain tumor'- I think she thought i meant neck tumour, though she said she thought there was absolutely nothing wrong with me and didnt even want to send me for tests. Do you think I should go back? Could it be a brain tumour? Im scared about it all.
