First of all, I'm 14 years old and have a history of panic attacks. I've had swollen lymph nodes for about 5 years behind my ears. Over the summer i suddenly became concerned about this, I worried so much that i made myself sick. I convinced my mom to get me a ct scan on my head to check for brain tumors, everything came back normal. Then i decided i must have a liver tumor(my cousin died of one last summer) so i had a ct scan done on my stomach and a blood test. Everything came back normal once again. For the past two months, my health anxiety has gone away. Now my lymph nodes have began hurting, i have headaches, im weak tired, my throat and ears are mildly sore, and my neck has been bothering me. I'm scared i may have leukemia. However, my mom says its just my anxiety. None of my friends take me seriously either. but what do you think? leukemia or health anxiety once again?? i had that blood test done 2 months ago and it was completely normal. Please respond, any help would be appreciated..
