Levaquin and backpain

I went to the emergency room for a dull pain in my lower back left side and was given an IV, a blood test, and a CT scan. After no signs of kidney stones were found the ER doctor sent me home and prescribed LEVAQUIN, IBUPROFEN, and METRONIDAZOLE antibiotics thinking that I might have gotten diverticulitis.
After 1 week of taking LEVAQUIN the side effects were right on! I could not sleep for more than 3 hours, I have anxiety attacks and my skin became dry no matter what lotion I put on it. I also had the runs and blackened stool ( and I thought I had a serious case of internal bleeding ). I have prolonged dizziness and nausea that even when lying down I feel like I'm gonna throw up. I have a lower center backpain that makes me feel strained ( like dead weight on my shoulders )and although my backpains have dulled a little bit but now, I'm still feeling muscle cramps in my lower and upper back, and have muscle spasms on my left inner thigh.
I always feel like I'm going to have a headache but I become lightheaded like I can't think straight and I am very anxious.
I have not have had any serious diseases and my checkups are always clean.
By reading these articles I have found relief knowing it could not be a serious problem I have, but could be major side effects caused by this drug.
I don't know what this drug cures but one thing i know is that it is very potent and dangerous for people with other health disorders relating to asthma, anxiety, insomnia, and others.

I cannot recommend this drug at all from what I see posted here today. And knowing the side effects are so extreme I begin to wonder why it is being recommended by physicians.

Should'nt they know any better?!
This experience has really awaken me to the new culture of drugs we have in the market today. Before I take another drug, I will find out more about the side effects.
