Dear singularity6, our hearts go out to you. All of us have slightly different symptoms, but like you I had the severe fatigue (that gets worse with what we usually call exercise), shortness of breath or breathlessness, and that awful brain fog which for me also makes reading and driving so difficult. And that frustration with expensive MD appointments and tests which generally show nothing. For me the road to find supplements which helped was one of trial and error, but I did eventually find a group of supplements which helped me, starting with simple anti-inflammatories. A round of physical therapy helped me get over the initial hump, focusing on exercises for balance, dizziness, breathing, and VERY mild exercise to improve stamina. Fortunately I was at an age where I could get social security and Medicare, so I can’t even imagine how difficult it would be to someone who needs to earn a living wage to support a family. You can feel so useless ! And humiliated. I’m so glad you’ve found this forum so at least you have people who understand you. Prayers for you.
