Same here...Got Covid late Feb-early March 2020. Then had to have my gangrenous gall bladder removed April 1st. So, between recovery from that and covid LC symptoms, I'm not sure when LC set in but, here it is close to 3 years later and am still dealing with LC "normals" ...extreme fatigue, brain fog, complete exhaustion following a simple 20 minute walk...But the internal tremors are truly disturbing...frightening actually, as my wildly creative imagination visualizes the tremors as the covid virus nibbling at my central nervous system.
