Lens implant symptoms and conditions

I was put on Prednisonsone for Uveitis, inflammation of the eye. He started me on 20mg at 9 pills a day, then each week it was lowered to 6 pills then now i'm on 3 pills and then next week it will be 1 1/2 pill and i'll be off. I got the puffy face, my feet swelled, everytime i hate my stomach bloated and hurt, my face and neck turns red, i stayed hungry although i fought the temptation of eating for not wanting to gain a lot of weight, which I don't think I've gained any. But now I wake up in the middle of the night and severe knee pain, it feels like my knees they are in some kind of device that is crushing my bones they hurt so bad. i caught a bad cough and it's been around now for about 2 weeks and won't go away, i told the nurse about it and she says, i probably just got what everyone else has gotten, just a bad cough, well what's if it's some kind of infection? I look like a chipmunk, my face is so puffy. When i get off these prednisone in another week I WON'T BE going back on them, no matter what the case. I'm in more pain being on them and have more side effects while on them than the problem i was having with uveitis. I think some co workers thank I'm over reacting, but they're not here they don't see all the pain and frustration i'm going through while on this drug. The leg pain just started this weekend and i Know i can't deal with waking up everynight like this in severe pain. Everyone just makes me feel like i'm over reactin and it's nice to know that somebody out there is going through the same thing. Any comments will be great.
