I too have had same issues, there is a website to report side effects after Covid shots, I don’t have it but have gone to site when I had literatures in front of me. It’s a reporting site only, no feed back , your pharmacy may be able to help you find the web site, and yes all the system in my body and no longer able to function, but my trigger was after injury to back after lifting table - 2 months after 2nd Covid shot, I did get third, but started wondering in back of mind.. if it could hv been shots
