I'm not sure where to post this, but seeing as I have suffered (sometimes still do) anxiety and panic attacks in the past I guess it's OK to post here.
Recently I started having B12 shots due to low B12 levels. I had shots in the past and can't remember this one symptom that happened after I had the shots - Black poops. I had my shot earlier this past week and the next day my poop was black. Before the shot it was normal in colour.
Just wondering if anybody else has had this?
