I took natures way activated charcoal for gas pains it caused worse pains then I started I also feel a lump in my stomach it has been 6 days and I still cannot have a bm. I also went to the hospital for this pain. They couldnt do anything for me because I took exlax which made me go but not the hard lump above belly button. The exlax made me dehydrated so they sent me home. I wouldn't recomend this to my worst enemy. So to all who read this before taking it please don't take it.
