Hi,
Dizziness is one of the most common reasons adults visit their
neurologist or general doctor. Good news is that dizziness rarely poses a life-threatening condition. It is important to get emergency care if the you have
severe dizziness or vertigo along with one or more of the following symptoms:
Severe headache,
chest pain,
difficulty breathing, numbness or
paralysis of extremities, vomiting, speech problems, seizures.
Dizziness could be due to:
1. Inner ear problems causing vertigo
2. Circulatory problems: Drop in blood pressure, heart
arrhythmia, anemia, hypoglycemia
3. Neurological problems: anxiety disorders, certain neurological medications, dehydration
Based no the history you provided specially fainting when standing I think the underlying cause is circulatory in origin. To tackle this, If I were your doctor I would first do a thorough physical exam then ask for ECG to rule out arrhythmia, measure your blood pressure sitting, and standing, ask for blood count test to rule out anemia. If resources are available and if a full diagnostic workup can be performed I would also ask for a brain MRI scan and EEG as a neurological baseline.
Another common problem that can lead to squeezing brain feeling and is easy to treat is eye problems. I would also ask you to get a visual acuity test, and eye glasses if needed. Based on the diagnosis treatment varies. I would recommend that you visit your general practitioner to get the aforementioned workup.
Take care. Hope I have answered your question. Let me know if I can assist you further.
