PredniSONE and nephro

I was put on 10mg. Prednisone 5 times a day by my rheumatolgist. This past Wed. I had to go to my GP doctor because under my right armpit it was red & swollen 2 inches high and 5 inches across. I was in agony. He flipped when saw how much Prednisone I was taking. He said that is what caused my armpit problem. He could not drain my armpit because it was too hard. That was when I just went to pieces because I wanted some relief.He put me on antibiotics and pain meds. He noted a yellow spot in the corner of both eyes and amde an appt. with an optomolgist. He told me how to taper off of Prednisone and I will go back next week. It has been 2 days since that visit and here are my new problems: white bumps on my tongue, numb tongue and lips, pus sores in my nose,bloating, bright red spots on my thighs, bruises I can't explain, moonface, pain under my rib area, I could eat eat our house like a termite, not sleeping, sweating. My husband half expects me to grow a new leg or develop leposy or something. I had no idea a drug could do so much damage so quickly.Who knows what new side effect I can get tomorrow.
