Hi All, I was wondering if anyone would mind sharing with me any experiences of Lactic Acidosis? I appreciate that it is incredibly rare, but unfortunately, the statistics do exist. If you have had it, was a cause determined? I am asking as I believe that a family member may have suffered with it, but it is undetermined. Just thought it was worth asking to see if anyone else has had symptoms that mirrored my family members. Thanks so much for any feedback, it's greatly appreciated! P.S... one of the tags is metformin due to LA being a rare but recorded severe side effect. I thought the tag may help get a greater number of responses when it comes to LA experiences.
