I also have had reoccurrence of original symptoms after a vaccination. Luckily they calmed down after about a week. Has anyone experienced getting their COVID symptoms hyped up after having another type of virus? I recently had a cold. A week after I recovered from the cold, all my original long COVID symptoms returned -chronic fatigue, stomach issues, headache, lightheaded, brain fog. I’m still dealing with these issues and hoping they will calm down again soon.
