For about the past week, I have suffered from a constant state of disorientation and feeling light headed. About a week or two prior to the symptoms I hit my head but it wasn t real hard, however my temple area was sore for a few days. I have seen a few doctors and had a CT scan and MRI done, with nothing major showing up other than cyst in my sinus area. They say the cyst ate common in the area I live due to allergies but they don t feel that it would cause the symptoms. Today I had a bowell movement and there was a half dollar size smear of blood on the toilet paper. I have had a small case of hemorrhoid before and noticed small streaks of blood on the toilet paper before but not this big. They took blood but said they didn t find anything. I m 28 Year old Male, Physically fit with no prior medical problems. Is there something else that can cause these symptoms other than post concussion symptoms? I m just concerned because the Symptoms have lasted so long.
