Phenol overload

We introduced two new foods in Kevin's diet, banana and orange juice. I noticed His behavior deteriorating and stopped with the banana after a few days, but he was and still is having terrible tantrums, screaming for ours straight at night and day. Developed a rash on his face on both cheeks and is now having a lot of sensory issues. It turns out that even being watered down the orange juice was too much for him. We are giving him no Phenol enzyme to help with this problem and his rash is practically gone after two days without the juice.
