Metronidazole and blood tests

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.
