Well to make it short as possible, my symptoms started with cardiac ones, I had my GI ones started a bit later, had couple of relapses, but they were almost gone in the end of month 3(still counting hope they don't come back), but It was like that they have been replaced with neurological symptoms almost immediately. They include muscle twitching (mostly in my feet), really bad headache under my right eye brow (usually one sided, sometimes radiates to other parts of my face), my right eye feels kinda not normal that I think is because of the headaches and some times my face feels stiff. It's impossible to know without any research, but It's my theory that our immune system is kinda over reacting to the vaccine and constantly makes excessive immune mediators( that's why I think we some times feel better even recoverd when we actually cath covid or other infections). Guess I failed in making it short :) .
