Hello sir happy to help you
Sir don’t be panic about it relax!
Symptoms you need to look for are headache, blurring of vision, nasal swelling,loose teeth!
You have history of steroid intake for 5 days only you are at risk but not that much!
Any other high risk like
diabetes, long stay on oxygen therapy and immunosuppressive disease!
Kindly keep taking precautions like saline gargles and nasal douching and be vigilant about mentioned about signs.
Thanks
