I am living alone and due to lockdown my cook is unavailable. As, a result I am having serious irregularities in my eating habits since 3-4 days. Friday I worked late and had oats porridge for dinner around 12:30 am. When I went to bed I was having headache and was feverish and so took a paracetamol. Next day onwards I am having constipation, looking a bright light is causing headaches and frequent short lived fevers. I am thirsty a lot and urinating a lot but no stool. However, there are no symptoms of cough or breathing issues. Please advice.
