My mother is feeling really weak and hungry. But she can't eat anything because she is getting a bitter taste . She is also suffering from cough. She also has a old medical history of dry blood cough,she gets it when the weather gets too cold or hot. She has medicine for that. She got vaccinated with COVAXIN on 3rd may. She was not feeling well before taking the vaccine. Neither she agrees to do a covid test nor she agrees to visit a doctor. I don't know what to do, . She doesn't has fever now. Is there anything so that she can eat properly. She became really weak.
