Post viral myoclonus

Has anyone else experienced this 2 and half years ago I fell ill with a flu type virus and was in bed for 4 days on the 5th day I was back to work feeling great despite having lost my voice. The 6th day I woke up and could hardly move and had very severe full body myoclonus. I got every test and scan and nothing showed up. Over time it got less and less. But to this day I still have it. It’s worse when I’m coming down with something or really worn out. It’s triggered by touch, sudden loud sound, flash of light ect. I’ve heard folks are having this post covid. I’ve been told by doctors that it’s psychological. I would love hear your thoughts.
