Hi there, the last 4 months have been pretty rough. In september i had blood in my stool and i really thought i had some sort of cancer (colon cancer) i had lots of test done (barium enema, barium swollow, blood tests, urine tests) you name it. Everything came back clean. I was feeling really good for a while and recently i got a ringing in my ears. It was pretty stressful but i was learning to live with it, then for christmas i had thought it went away. After christmas i got what the ER doctor called Gastroenteritis (Stomach pain, vomiting, and nausea) Ever since then i have felt like crap, i feel dizzy, headaches, muscle twitching, nausea, vision problems, and just over all like crap. I am wondering if maybe this could all be associated with anxiety??? my doctor gave me Anxiety meds and told me not to worry that everything was fine, but i dont feel fine...my headaches arnt to the point where i cant handle them but they are there and it does worry me. My dizziness doesnt last all day just some part of the day and the nausea isnt all the time either. I am afraid i might have a brain tumor or something like that. The more i google symptoms it seems the more i get symptoms. Is it possible that i think so much about my symptoms that they might be in my head? lor could anxiety be causing this? what should i do? i think i might go back to my doctor and as for a CT scan to make sure i dont have any brain tumors.
