The timeline indicates the precipitating factor for your illness could have been the vaccines. The symptoms and etiology of vaccine long-haulers resemble those of Covid long-haulers. I agree with the recommendation to see a neurologist. In addition to the symptoms that suggest autonomic dysfunction, the tight tendons in your feet could be neurological. The first symptom of my vaccine injury was tightness in my feet and calves and muscle spasms in my feet These were later confirmed to be neurological. You can learn more about vaccine injuries by joining the Neuro V Long-Haulers Facebook group.
