I thought that I had a TIA on June 19th, then theses symptoms emerged suddenly and have remained every since. These symptoms are: constant fatigue, sensitivity to light, dizziness, extreme-constant head pressure which includes the neck and shoulders. My neck is stiff but not painful. Tendency to clench my teeth, nausea, I ve not had an MRI. I have had CT scan using radiation, cat scans, blood tests, x rays. All showing normal. I don t have arthritis. I don t have lupus. I don t have anxiety. I don t have high blood pressure or cholesterol. I don t have cancer or tumors.
