Was covid+ 6mos ago. feeling like i'm about to start getting flu like syms, itchy throat and slight fatigue. been in contact with covid+ person.diagnosed with hyperthyroidism but levels have been within range. more severe covid experience possible?

All bets are off with this varant. A second covid infection is possible and may be worse than the first If I were to guess, I'd say you may be experiencing a noncovid viral upper respiratory tract infection but you could isolate and test in a few days depending on symptoms to be sure. Most people I've spoken with had impressive aching muscles ,dry cough little nasal congestion with this variant.

Trust you got flu vaccine? If so flu not likely.
