Yes! I wrote down symptoms as they occurred in early 2020. Covid hit me neurologically. I’m pretty sure I was only infected once, so all these symptoms have been from that original Wuhan strain. Initial symptom was amnesia (likely a focal seizure) and migraine (never had one before). The following week I was OK did not feel myself. I got the fatigue about a week and a half after initial infection. Then weeks later the nerve pain. I had a couple of other small focal seizures (small memory lapses) that first year. I was seeing a neurologist before the term long Covid existed. Doctors could find nothing wrong. Then everything went away. I started to feel great - felt mentally sharp, started walking daily and losing weight. Fast forward a few years and I’ve lost 50 lbs and have no appetite, and the brain fog is worse than ever. I had a lot of anxiety, but did not take meds for it, because I felt the anxiety was caused by the pandemic, and I felt I could manage it. Add poor sleep getting up 10-15 times a night. As you mentioned, I also found myself getting more emotional than before, and had a few episodes of sadness and weeping that were not normal for me - I am normally a cheerful and optimistic person. So lots of things were not ‘me’. Three and 1/2 years after initial infection I had a seizure that required an ambulance and hospital, and was diagnosed with Epilepsy. So to answer your question, yes, Covid symptoms seem to come and go over time. It will take years for the medical community to catch up with what we are experiencing..
