I don't want to buy a whole lot if ds has a reaction to it. He is having a breakout from RTF Alimentum and I think it's hives. Tiny red dots on abdomen and near ears and pubic area that sometimes disappear throughout the day. Some are slightly raised/blistered on his head. Not sure if they itch or not. Seems pretty content. However, I would like to try neocate. Can anyone recommend where to get a small trial?
