hi... i get really dizzy and feel really sick, then i over heat an get a cold sweat and pins and needles in my arms and hands then have a blackout and faint and have a pain in my chest and sometimes find it hard to breathe, could you tell me what would cause this please as it really scares me as i drive alot...
HiT hanks for your query. Based on your query, my opinion is1. Dizziness, fainting is usually caused by hypoglycemia or anemia.2. Hypoglycemia means Chat Doctor.  Get your blood sugar level checked.3. Anemia needs to be ruled out. Get a Hemoglobin level checked along with red cell indices.4. Transient ischemic attacks can be causing you these problems. This needs to be evaluated. Get your Blood pressure checked to rule out hypertension.5. Also get a lipid profile done to know your cholesterol levels.6. Chest pain can be due to angina or gastritis, so ECG is needed. Hope this helps. Regards
