hey bigjay, I had all of those side effects you mentioned, plus racing heart with almost no exertion, high blood pressure (been low my whole life) plus from head pressure I started stuttering and had trouble walking as my right leg was very weak, kept tripping and dropping that foot, and could not walk without contacting thinking about where my feet were going etc. Constant cramping and thirst, pain over kidneys, headache for 5 months, insomnia. There are several other problems I had, but so many to list, one day I'll have to share my full report. What I can say is that around 7 months I started regaining my balance and ability to think and walk. At 9 months (now) I'm doing pretty well, I can walk fine although my gait still feels weird and when I'm tried I still trip over my right foot. but have several lingering problems the worst of which is a huge reduction in my bodies ability to heal itself or recover after extreme exercise. I used to recover within a day and never got cramps at all.... and now I feel I don't recover well at all. Now I often have sore muscles and cramps a week after exercise. My worry is that the vaccines affect DNA repair (not that I have any proof of that) and that I am not able to recover completely from weight training, sports or minor infections etc. It basically feels like I've aged 30 years instantly after the shot. Been exercising everyday my entire life, these side effects were no coincidence, they started 35 minutes after the Moderna mrna vaccine. hang on Bigjay .... it does get better, I have heard it can take some people 15 months to recover cover completely.
