All 58 of their #LongCovid patients had chronic #epipharyngitis with complaints of fatigue, headache, or attention disorder. 90% were moderate or severe. Epipharyngeal abrasive therapy (EAT) alleviated symptoms, even when it didn't reduce inflammation. "The mechanisms of EAT are reported to be the anti-inflammatory effect of ZnCl2, the blood-letting effect, and #vagus nerve stimulation." This treatment may be an easy option to relieve some chronic #SarsCoV2 symptoms.
