Hi, i recovered from mild covid at home 1 week ago. Since 17th day of covid symptom onset, i m experiencing severe dizziness, throbbing headache, intense pressure in ears and sometimes tinnitus. All these problems arise at evening and keep worsening all night causing insomnia. I feel fine in day time. Sometimes acute episodes of vertigo cause bad nausea. I have started vertin 16 tds 3 since 3 days. Kindly suggest
