Corticosteroids are fun, fun, fun- I woke up covered in rash, had problems to open my puffy eyes, nearly 10 pounds heavier (all water weight but still)... I too wore sport shoes (2 sizes bigger) cause my feet were so swollen I couldn't fit in anything else.
Commenting on weight gain is tricky- I wouldn't ever male or female, T or not T.
Not all ED Ts are thin- had one who was fat (Europe fat= overweight in US?) and she was very good.

I know my T was ill, he cancelled few appointments due to health reasons, I asked but he didn't want to talk about it. Fair enough.
