Sorry for what is going to be a long post, but I am going to put it all out there. November of 2009 I went and ate with my family at my sisters house and got sick. My brother and brother-in-law also both got sick with what seemed to be a stomach bug, we all had severe diarrhea and vomiting for 2-3 days with body aches. They both recovered to normal health but I have been suffering with some chronic symptoms ever since. After the diarrhea and vomiting passed I had a chronic dazed lightheaded almost off balanced feeling everyday since. I also started getting optical migraine headaches(which I had never dealt with headaches ever before the sickness) about one every 3 months. My vision also changed to where I got eye floaters along with seeing sparkles in my vision anytime I look at anything light colored that is bright(example would be the sky). I have also been chronically tired and lethargic which in all honestly is the complete opposite of my normal self before the sickness. This all started and has stayed with me since I had that stomach bug, before I got sick I was completely healthy and loving life. Now everyday is a struggle just to get up and go to work. I have been to an ENT, Ophthalmologist, gastro doc, and a neurologist. I have had countless amounts of blood work, 3 CAT scans of my head/inner ear, MRI of brain, endoscopy and colonoscopy. I have had vision test and hearing test and I have also went to a chiropractor. The reason I posted under this forum is because the most annoying symptoms for me is my vision and dazed/lightheadedness feeling. It just feels like there is a lot of pressure in the front part of my brain. I thank you in advance for your response. I am a 28 year old male.
