Hi, my sister had been infected with Covid-19 during April /May 2021, she received her first covishield dosage on 24th July 2021, since then she has not been able to sleep peacefully during the Night, She wakes up with complaints of breathlessness (especially during the night),                               During the day, she keeps getting fatigue and loss of appetite and hence low on energy. Please help me get the right consultation🙏. Regards Ravindra
