Metronidazole and brain

six months ago my dentist prescribed 500 mg and 500 mg of penn every eight hours for five days,, along with vicodin for a horribly painful gum infection in my root canal. To this day I wonder if I will fully get rid of all side effects of the Met. After 3 days I was soo dizzy and with extreme blurred vision, the pharmacist and dentist office stated it could not be the ant but the vicodin. I stopped the vicodine and just stayed with Motrin. I had the worst vertigo and blurred vision you can imagine, I felt like an infection was now in my brain, (yet was not) I felt like I had a toxic infection in my body. I would fight to concentrate mentally, I was very fatigued and sick feeling. This went on long after the tooth pain. It took about three months of strining for mental concentration, dizziness, toxic feelong to begin to go away. By the fifth month I could finally feel my personality had returned. Yet my vision has not and has only gotten worse. My dizziness is every so often. During the first months I kept running back and fourth to my doctor with no avail. It was the eye doctor MD that said he was very suspicious that I had an toxic allergic reaction to the Met. Between doctor visits, eye doctor visits, cat scan I have run my medical bills high. I am extremely worried about going blind.
It has now been six months - my health, my vision, my family, my job, my personality have all suffered from this.... Don't take this drug............

within two days of taking metronidazole for a gum infection i had horrible pins and needles the worst crushing headace ive ever had anxiaty panic attacks and couldt sleep for a week this medicine is the nastiest side effects ive ever had .i just got back from hospital where ive been for two days as my symptoms were so bad docs thought the infection in my gum had traveled to my brain, but after a ct scan,lumber puntcture, blood tests all came back clear they decided it was the tablets. it will take me a long time to get over this , i would advise anyone with a history of panic attacks,depression or headaches not to take metronidazole.
