Good evening sir/madam My wife got Corona positive on 26/4 with test confirming it. However she was under home isolation and took the prescribed antibiotics and vitamins. In between her CRP and dimer test was raised and doctor recommended for steroid and blood thinners for 10 days time. On 18/5 after she felt better and more than 17 days of covid has passed we did rtpcr test for her and the reports were negative this time. Now after 1 week of further rest she joined her office. However she is having problems of slight chest unesiness and at same point on back occasionally, also she had little cough and back pain. The temperature comes in range of 98.5 to 99.8. However her spo2 is between 99-98. Please suggest what course of action to be taken and why is this happening after recovering. Is there chance of reinfection also.
