I'm a 23 year old male. I am a hyperchondriac... Whenever something is wrong with me I Google it on the internet. I have had a couple of panic attacks. I recently had a colonoscopy done because I thought I had cancerous polyps.. i In 2009 I thought I had a brain tumor. I was experiencing headaches and numbness in my toes... I went to the ER and had a CAT scan conducted. The results were normal.. Once I heard the results were normal my pain went away..On December 19 a friend I went to high school with passed away from a brain tumor. Christmas Eve I started to have a throbbing pain in the front of my head.. A couple of days later my head started to feel heavy and I felt pressure. I've also have tingling and numbness in my hands and feet.. Also, sometimes I feel dizzy and loose my balance. I haven't been myself lately.. I've lost my appetite, I feel weak, I stay tired, and at times I feel disoriented (out of it).. I'm making an appointment tomorrow to see a neurologist,,, I think I'm tricking my body into believing I have a tumor.. Does anyone else have similar problems???
