Thanks - the only thing I would add from my own experience & I can't speak for everyone but steroids can produce quite a distinct effect/ pattern in blood sugars that is slightly different & not all medical professionals are used to dealing with it. For example with my consultants help we worked out I needed to take my basal insulin in the morning and not the evening that is usual (steroids raise blood sugars through the day from around mid-morning & then can drop quite significantly over night so much higher hypo risk overnight) I also have a much higher insulin to carb ratio at lunch as the steroids kick in & then much lower in the morning/ evening.
Trial and error & ive had nearly every side effect from steroids but once my diabetes consultant got past I wouldn't ever likely be able to stop them & needed them to breathe (helps that he saw a very bad patch) we started getting along much better
