I am much older 56, but yes, I too have pots now, not after covid rnd 1 in Nov of 20 , but after rnd 2 jan of 22. I went thru all the tests and they say I stay in sinus rhythem so its autonomic, Nerves. So far no fix. Sorry wish I could help you. Mine is worse durring a flare. When in a flare everything is worse. By flare I mean, headache tired(worse than usal) muscles tenser, sorer...My flares come by over doing. Dehydration. Stress. on a good day I am up to 20 min walks(not fast paced). On a bad day the typical 10 min will do me in. a shower 160, dishes 140... pace your self, dont over do. Learn your breathing exersizes, deep belly breaths, exhale thru mouth slowly, it calms you...good luck, prayers!
