At this point I am going to give you an account of my past 14 months health and how I know it is related to the covid virus.   i am sure i have had long covid  from december 2019 or january 2020 to the present based on symptoms i incurred on these dates. On my first night I ended up vomiting my guts out at 2:00 in the am. The following 2 weeks I had constant diarrhea.  At the end of those 2 weeks,  i ended up in emergency room. And this all happening when  i haven't' vomited in over 30 years.  vital signs and blood work were good at the hospital and the drs were confused as to why i felt so bad. i returned home the next day where our permanent home is,  and 3 months later the covid thing surfaced. at first being thought of as a respiratory disease. then in the past months it is surfacing that it may now be considered a gastrointestinal disease that progresses to a respiratory disease. after checking the five main symptoms of long covid i discovered that i have at least 3 of the 5  common symptoms for this. Those being extreme fatigue, joint pain, and cough. In addition to the long covid symptoms, I have encountered tasting issues on and off again.  I have had many discussions with my primary care doctor, and no results or conclusive information came from my inquiries. Then on feb 12, 2021 I got my first moderna shot. About 2-3 weeks later I encountered a sharp pain in a muscle in my neck left side. Shortly thereafter I got very light headed. Then another  week later while  driving a motor home, I encountered a frightening experience with my eyes, and the neck pain and soreness was still there. My vision was very blurred and I was seeing double vision at different angles. I ended up at the medical center and was admitted for 4 days. Before I was admitted, I saw a local ophthalmologist here and he diagnosed me with a condition known as ?edema in optic nerve, inferior, consistent with optic nephropathy?. The symptom I had to get me to the doctor was I was losing eyesight in my left eye. After hd steroid treatment for 4 days, and a plethora of tests, including spinal tap, multiple mri?s, and probably over 20 blood tests (11 at one draw), I was released 3-18-2021 and still can?t see above the equator line of my left eye. And I also am extremely sensitive to light. I also have sensitivity inside my eye as best described as a soreness, especially when I try to look upwards. I have a follow up appt with the ophthalmologists that I first saw that advised me to get to the hospital. And that is on mar 26th 2021.  to mention another point of interest, my granddaughters boyfriends mother is a charge nurse at the emergency ward at the hospital, and she has said that they also have recently encountered emergency patients, who have recently received moderna, and are also having issues with eye problems. What problems in particular, I haven?t a clue at this time.  This is at the very least, extremely alarming to me, and I have no idea whether I may completely lose all function of my left eye., or not. But I adamantly feel this should be investigated by the cdc and any and all other agencies that should be involved.  I would be willing to have further discussions via phone or whatever to help you out with an investigation.
