Frustration with finding words when needed. On the strange side, suddenly names pop up that have no connection with what I'm doing, which I've had to look up to see who they were. Making bread one day I suddenly began singing a song I must have sung in the 3rd of 4th grade. Not only did I remember the melody but all the words as well. 5 minutes later I could not recall it. These are just 2 examples. Now have buzzing in both ears, fluctuations in body temperature in minutes. Some foods I like don't taste the same or taste awful. My smell comes and goes. I've had MRI's and EEG's. Both normal. Past problems have been chest pain, terrific jaw pain for weeks, sharp pain behind eyes, leg pain, digestive problems. All testing was negative. Had Covid March 2020. My primary doctor scoffs when I've mentioned Long Covid.
