From the past one month, I start getting fever (4 times)(every week) (gone after 2-3 dose pcm)(temp. 101.4max), sore throat (one time)(gone after 3 Azithromycin) and watery diarrhoea (okay without medication only ors). No cough, no breathing problems. From the past 15 days, I am suffered from lack of sleep and only worried that what happens to me if I got infected with corona as no one is to take care of me. I am in a high state of fear and worried about my health and treatment as there is very bad situation of hospital in mumbai.
