I was prescribed Levaquin 3 days ago for a sinus infection. After 3 doses, I feel worse than I did when I went into the doctor. After taking my first dose, I woke up with a terrible sore throat. Then came the excruciating shoulder pain. I can't even lift my arm up it hurts so bad. I'm extremely weak and get dizzy very easy. I am also experiencing chest and leg pain, sleeplessness, and irritability. I have broke out in a rash on the back of my arms. I've read the info that came with the medication at least 5 times through and kept telling myself that it couldn't be the medicine making me feel this way since it is supposed to make you feel better not worse. After reading this, I am not going to take the medicine anymore. I put a call into my doc to see if he will prescribe something new and I am considering going to the er to get some relief from the pain I am in.
