Where do I begin. I've been on prednisone for about 3 months now, and I feel like it has ruined my life. After having my son in February of this year I went for my 6 week check up and found out that I had high blood pressure and my kidney function was low. Before this I was pretty healthy. So, I was put on 30mg of prednisone in hopes that it would reduce or erase the inflammation. It reduced it for a while, then it went back up. While on the darn drug, Ive experienced moon face, weight gain, Im always hungry, acne, shortness of breath, and paining in my legs and back. The worse side effect has been the mood swings and anxiety, probably because it took something terrible happening to realize that they were really happening. My boyfriend told me that the drugs were making me act different, but I just thought he was picking on me as he did with my weight gain. Turns out, I have read everyone elses post and realized that many people experience what he says I've been going through. As a result of my mood swings and being so mean and demanding, my relationship may be over. I wish that he would understand that it's not me, it's the medication, but I can't convince him. Thats weird, especially since he pointed it out to me months ago. So now, I hate this drug. It's not making me better and it was a contributor in ruining my relationship. I want to just stop taking it, but Im scared I will get even sicker. There is no hope here.
