Levaquin and moon face

I am scared to death after reading what everyone is going through. I was put on Levaquin for 10 days and got to day 9. My joints ached so bad I thought I had arthritis, and even had my Dr. do blood tests for it (I had no idea it was the Levaquin). I am only 35 years old and never worried about arthritis before this. Also, within 5 days I started developing hives all over. Again, I was stupid and didn't realize until day 9 that the hives were because of this med. I told my Dr. and he told me to stop taking it which of course I did. I assumed the hives would go away after the med was out of my system. But a week later the hives were unbearable. I was put on prednisone (another issue altogether) and that helped the itching, but now every time I try to go off or back off the prednisone the hives come back- and they are terrible! Now my Dr. thinks the hives were from something else because there is no way that the Levaquin is still in my body. But after reading what other people are going through on this med, I am convinced this stuff is as everyone says- POISON!! I am so worried about the joint and hip pain that was so bad I couldn't stand for long without excruciating pain in my right hip. It felt like I had a one hundred pound weight just sitting on it. And my hands were the worst. I have a newborn and could barely pick him up without worry that I'd drop him. I don't know what to do.. Is there anything to do?? I'm still on the prednisone, and have been for a month. I need to get off of it but every time I do I itch so bad with the hives that I cannot function. Also because of the prednisone I noticed last night that I am getting "moon face" my face is swelling up and there are a million side effects from that drug too. How long does this last? Has anyone else fought the hives that come with this? Please help me, I am so scared!
