@estrada53 I too am on 5 mg of prednisone. It has not caused any problems that I was aware of except for the bruising on my arms, until I discovered that it had caused my osteoporosis.
The bruising is called purpura and it can be helped by applying a topical (approved by my transplant team). The transplant dermatologist at Mass General prescribed it for me. It is often used for acne too! It toughens your skin a bit to prevent the bruising. There is also an OTC cream made especially for purpura called DerMend. That helps too.
Did your weight gain happen immediately? I am really struggling with my weight currently and have been since last summer, which would have been almost 3 years post-transplant. I suspect I will always have to take prednisone because my blood numbers (platelets especially) run low and prednisone helps with that.
If you seek the prescription cream, be aware that it is expensive and not covered by insurance, but if you use the app GoodRx you can find it priced fairly reasonably. I haven't used it for a while, I primarily didn't want those bruises limiting me in getting a dress for my son's wedding last August.
