I have taken Avelox before with only minimal side effects nausea and diarrhea were the only ones I got but they were enough. I have been suffering from chronic sinus and ear infections for going on two years now. My doctor gave me samples again of avelox on Monday. Last night I had to be rushed to the hospital. After throwing up all day I got a severe headache. I felt dizzy and out of sorts all day but when I couldn't take the headache anymore I tried laying down. With this medicine you can't take any pain relievers so I thought if I just went to lay down maybe it would ease up some. Well it didn't, and before I knew it I was shaking uncontrollably with tremors and could no longer put sentences together. My head hurt so bad I just wanted to stab myself to make the pain go away. At the er they gave me an IV with something to help with the headache.Anyway after taking a Ct scan and not seeing anything on there the er doc gave me the ok to go home and gave me a script for pain meds. I was having hallucinations, anxieties, and could not speak correctly. I am still having trouble making sentences, I am stuttering, which I have never done before. And I can't get words to go together to make a sentence. The Er doctor wants me to follow up with a neurologist. My tremors still haven't stopped and now I sound like the guy from rain man when I am trying to make a sentence. This is pure torture and I feel like I am in someone else's body.
