My father is 73 year old and recovered from covid before 9 days . For fist 5 days he maintained 95+ spo2. After that his sugar level increased even though being non diabetic , doctors told me it is side effect for steroids. and he was under treatment for 4 days again, now sugar and bp both are under control, but now I can see spo2 maintaing 86 to 93. Please help if I need to admit him in Hosp again or what can be done.
