Chronique fatigue

[lostintransaction]

32 yr old male, 5'6, 120 pounds. I have had this issue for 3 years now and don't seem to be able to find help despite seeing a fair number of doctors. It all started one day as I stood up after lunch, I felt something was off under my solar plexus and my heart started racing. I panicked and asked a colleague to take me to the ER where I had a EKG and an echo. They didn't find anything abnormal and sent me home, saying I was probably stressed. I followed up with a cardiologist, wore a Holter monitor for 24 hours, and had a regular stress test which both came out normal. It happens from time to time. I would stand and feel this weird feeling in my chest as I stand, it would mount slowly and then my heart would start beating faster and faster. I usually have to sit down (unable to stand) with a sense of panic. I am extremely pale during these episodes. Given the exams I had, my doctors say that a heart issue is unlikely. However, I still fear it is a possibility as I am easily fatigued and feel chest tightness when I do any kind of strenuous activity. Another possibility is GI issues as for some reason, I blurb a lot after these episodes. This condition is making my life impossible and I live in a constant state of stress of these symptoms occurring and I am generally exhausted. I am super pale most of the time, which is strange given my ethnicity. I thought about anemia given the paleness and the fatigue but my blood work is fine iron and red cell wise. Let me know if you have any idea!

Have you had your Vitamin D and B12 levels checked?

Vitamin D 25OH

Closer to 800 is better

Also. How is your intake of magnesium, potassium, sodium?
