Ecv symptoms and conditions

To make a very long story short, I took this medication for 3 days for a sinus infection and misdiagnosed bronchitis. I was diagnosed on Friday with regional pain disorder. Has anyone else heard of this? My doctor is also saying I have a herniated disc and fractured tailbone, this was also news to me, no pain until after taking the Levaquin and the only back pain I have is leftover from EMC/ECV testing. Also when will the nausea go away? The pain medications seem to be helping with the insomnia, but now I have crazy dreams and just want to get off of this ride. Any help with this would be appreciated as I'm not sure how much more I can stand.
