clostridial infection
"I have been taking metronidazole 500mcg 3 times daily for 7 days for C-Dif.  The side effects are awful, stiff neck, painful urination, back, leg, hip, knee, ankle and overall joint pain are terrible.  I reported this to my MD, who encouraged me to keep taking the med for 10 days to be sure the c-diff infection is gone.  So, I am still taking it.  Right now, I only hope that once i manage 10 more pills, that the pain and hurt will go away.  This is without a doubt a very toxic medication and not much you can do except take it anyway.....  Can someone out there let me know if the joint pain goes away after you quit taking this stuff?   Is there something that I can do to avoid permanent joint damage?"
