My mother, 71 got COVID around apr 14th symptoms started and apr 17 the test came as positive. Her blood pressure has been moving a bit currently at 150/81 (it has been 180, 163 and 135). The medication is on. She is also diabetic and has thyroid. She is complaining of extreme fatigue multiple times in a day. Her covid symptoms had gone, but she recently is feeling symptoms of cold in nose and throat. Please suggest what should be done.
