" at least you know what is causing some of the AF, that must be a huge relief for you." somehow yes is true finally i have some answers. But they came with really big efforts for me and after 3-4 years of "unknown ilness".
When I caught the CMV they treated me with Antibiotics and that make candida out of control an started AF big time with everything you know; big crashes fatigue depresion... they told me its in my imagination for nearly 3 years while I was carrying 5-6 chronic infections.
I had to quit job and go abroad with all my savings to start obtaining different results to tests and approach. Too see diff docs and labs than in my country...I was about dying twice in ER...
But yes its a relief that finally I know what is going on with me even partially :)
Oh...viruses are not the only culprits you may have (if your AF its infection related). Bacteria or mold exposure or...
