Hello Doctors , I am placed in usa. From past 8 months I am facing continuous lightheadedness , feels like I am under influence of something like alcohol. I had chest pain and blood pressure went upto 150/100. Emergency Room doctors said it was panic attach. It happened twice with me. Now in last 8 months I have done 1. Holter Monitor 48 hours 2. ecg and ekg 3. Chest CT SCAN 4. Heart CT scan 5. Heart Calcium Score which is zero 6. Barium x ray test for stomach ulcer 7. Brain MRI 8. Lipid profiles , blood work 4-5 times 9. H Pylori - this was positive and had 14 days antibiotic test. Had breath test again to make sure it's eradicated. Every report comes as normal. As per doctor i am completely fine. They even dont see any anaemia or thyroid issues but everyday and night I face these issues. My age is 30 , height 6 feet and weight is 90 kg. Blood pressure most of the time is around 135/90. Had ECG during the time i was facing pain. Please help me to find a way.
