Can't handle acidophiles

I have tried acidophiles over the last 20 years. I also get sick from it. A very acidic stomach and outbreaks of cold sores or infantigo below my lower lip. I try taking it to help with my candida, but 2 or 3 days of just 1 capsule a day, and I get sick. I have been to multiple alternative health professionals for various reasons, and I always ask about this problem I have with acidophiles. None of them have any answers. Recent I was seeing a NRT guy. I took a bottle of acidophiles in to be tested. He said my body hates the stuff and I should never take it again. He was surprised, and he did not have an answer why my body hates it.

Can anyone suggest why my body cannot handle it?
