<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have what I discribe as lightheadedness that only lasts about a second. This happens 10-20 times a day. It is just more of an odd feeling in my head. I don t fall and I m not unstable at all. No headachs or other pains. The lightheadedness is very light but notacable for sure  <response>: Hi, Why suggest a medication as opposed to looking for the UNDERLYING CAUSE? Theres virtually nothing more vague to assess and treat than the symptom of lightheadedness which is even sometimes hard to pin down from patient to patient as to what they exactly MEAN? Make sense? If this is something thats recently started then, check out any new medications you may be on...especially antidepressants, heart Chat Doctor.
