Levaquin and magnesium supplement

About a month ago I was given Levaquin, for Pneumonia. After about 5 days my face and neck swelled up, Then came the Prednisone at the hospital. I have never in my 38 years not been able to control my own body. I do take Zoloft,and Xanax for anxiety. No one said I would have a problem walking (legs are not working properly) eating,sleeping, Buzzing in my head. Unable to lift my 3 year old let alone care for her, I get extremely fatigued easily. My Husband has missed a week of work, and if your like us....NOT GOOD. Even trying to type is hard I must look at every letter, It's like I REALLY have to think to make my body move.My kidneys feel like balloons in my back when I lay down,Uncontrollable crying. I can't believe this has happened. We have been going through this the whole month of May.Is anyone able to control the shakes? Even my head is shaking??? I suppose if I had tried hard drugs ever, this might be what it's like. I Pray someone can help me. I am so afraid of what is happening to my body. By the way, when they put me on the Prednisone they did not give me a taper... Had to see another Doctor for that. So as I sit here today, hands shaking, head shaking, knees feeling to loose to walk on them, Hard to breathe, or even to think the way I could a month ago. SOMEONE PLEASE HELP ME...
