Dexamethasone - can side effects appear after any dosage or time period using this drug?

I was prescribed 32 mg (16 mg each time) of dexamethasone from June 12th through the 19th, for the first time. This was also after a course/dose pack of methylprednisolone. By the morning of July 5th my feet (and hands, somewhat) were swollen and by the end of the day, my ankles, too.

Curious because the swelling seemed to come on so quickly. Thank you.
