I know someone's case who got it 3 times. The first 2 times full recover in no time. The third one took couple of months and now feels tired all the time, lost all sense of taste and smell, swollen tongue, body pain of sitting still due to the compression of muscles.

This person told me it was sure it was related to COVID because there was nothing before or after it and that was the only thing that happened.

Kinda sucks to thing that everytime it might be a chance for that or worse
