It's been around 20days since he has covid. He is in recovery phase and not facing much issues. He had x-ray and CT scan done, there was some stomach infection and the CT score was 9/25. After that the doctor gave the medicine and he started Recovering. Things got better. But he wasn't having food properly. There's continuous weakness and tiredness from last 10days. He's always sleeping about 12-14 hours a day. Don't interact much and always seems irritated if someone speaks up to him. Now he is also having some throat pain while chewing the food. Is there anything to worry about? Or do we need to do any tests further.
