I am not an anti-vaxer either but am sure my problems, starting in April, 2023 are from the vaccine. Vertigo, chronic fatigue, heart palpitations, high blood pressure, brain fog, exercise intolerance (I was a very active, exercising person), heat intolerance are all symptoms that are chronic or flare up at times. I have been to an hematologist, heart specialist, pulmonologist, allergy specialist, endocrinologist, and had every blood test and scan know to man, all finding nothing significant. The best practice I have learned I learned here from other suffering folks. Pacing. I have finally achieved a level of activity where I can do some basic house chores, some shopping and a bit of exercise. Not always on the same day. I have pushed to exercise and I'm able to do about 20 minutes most days. Pushing myself past where I reach tired (sometimes just cutting up veggies) results in a day or two set back. The key is immediately stopping activity when the fatigue kicks in. The first year, not one doc would talk about the possibility this was caused by vaccines. I was told I needed anti-depressants, or probably just getting old. I even had one doc excuse himself from the room saying he would be right back and then, he never came back. (no longer my primary!!!) I have given up on doctors. They wear blinders and do not look at the whole person in front of them. I hope you find some relief. Pace yourself and take care.
