Vagus Nerve Stimulation for Post-COVID Syndrome

The aim of this study is to increase parasympathetic activity and decrease the severity of symptoms by providing vagal stimulation with the t-VNS method in order to suppress the increased sympathetic activity in patients with prolonged Covid symptoms.The main question\[s\] it aims to answer are: Question 1:Is left ear transcutaneous vagus nerve stimulation effective in suppressing the symptoms of patients in Post Covid syndrome? Question 2:Is bilateral auricular transcutaneous vagus nerve stimulation effective in suppressing the symptoms of patients in Post Covid syndrome? A 5-minute heart rate variability measurement will be performed to measure the effectiveness of vagus nerve stimulation in participants.HRV is a non-invasive method used to evaluate ANS activity and is a measure of heart rate change over a period of time
