I took only 2 days' worth of flagyl (metronidazole) 3 months ago. After the first 2 days, I noticed tingling/burning in my feet, so I didn't take anymore. It initially lasted about 3 days. Then, I was completely symptom-free for a month. Then, the pain came back. It's been off and on since, but has seemed to have gotten more intense and is sometimes in my hands as well. I've seen 2 neurologists about it, each one denying to have ever heard of this side effect, even when presented with its documentation. It's VERY frustrating, and quite scary. I have a job that is not at all conducive to taking pain meds. Plus, I don't really want to just medicate the problem when no one has even addressed it or tried to fix it. Also, every pain med or neuro med has just as high a side effect profile of metronidazole had. I really don't want to deal with any further complications from medications. Does anyone know anything about this, how long it lasts, who to see, if there's a doctor that treats it? Please help!
