PredniSONE and uvula

I got a large dose. I think 120 mg. in a shot. I had strep throat and had severe tonsil swelling and the uvula was enlarged at least three times the normal size. I'm concerned now as to what to do next. I have a prescription for a week where I wean down the dose to I believe, 80 mg for three days, then to 40 for three or two days (I'm not sure cause I didn't get the prescription picked up yet. I just am remembering what the doctor said. ) I'm so concerned that it'll mess me up! The dosage continues to one pill for so many days and then to a half. The swelling has subsided substantially, and it really helped. I don't have any other symptoms as yet. Maybe a sour stomach. I'm afraid of the symptoms and any weight gain.
